The PowerPoint Online Guide: How to Make and Present Slideshows Anywhere

Over the past thirty years, PowerPoint has become synonymous with presentations. Give a speech, present a new product, share finances in a board meeting—all are typically done with a PowerPoint presentation. That’s easy enough if you’re presenting from your laptop and have Microsoft Office installed.

Or it can be far more difficult. You might need to email your slide deck to the event organizer—and hope they have the same version of PowerPoint installed. Or you may carry your PowerPoint file around on a flash drive to open it on the presentation computer. Neither are great solutions, especially for all the times you need to make a last-minute change to your slides or if you don’t typically use Microsoft Office.

A Quick Guide to Office Online

It starts with Office Online . Launched in 2010 as Office Web Apps , Office Online today includes simplified, free versions of Microsoft Office’s most popular apps: Word, Excel, PowerPoint, and OneNote.

If you’ve ever used the iPad or Android tablet versions of Office, Office Online will feel instantly familiar. The basics are the same. Each Office Online app includes an Office-style toolbar with Home , Insert , Design , and other tabs to organize core editing tools. Office Online apps don’t include all of their Windows features. They include instead a focused set of editing tools that, for most documents, spreadsheets, and presentations, are all you need.

The big difference is that the apps are online. Instead of emailing files back and forth, or syncing changes via OneDrive or Dropbox then sending messages to colleagues when something’s finished, changes happen automatically in Office Online. Your team can open files at the same time, make changes or add comments, and Office will save and sync it to all your OneDrive accounts automatically. Office Online apps also work everywhere. Open any browser, go to Office.com, and your work is ready to pick up where you left off.

Office Online is free for personal use—log into Office.com with a Microsoft account and fill up OneDrive’s free 5GB of storage with all your Office files. A business version is included with Office 365 for business and enterprise accounts as well.

The basics are the same. If you’ve used PowerPoint before, you’ll feel at home in PowerPoint online. Here are the things to keep in mind, the tips to help you work efficiently in your browser, and ways to work around Office Online’s limitations.

For your number crunching needs, check our Excel Online Guide to learn everything you need about Microsoft’s free Excel.

A Quick PowerPoint Online Tour

Ready to make a new presentation? Open PowerPoint Online at office.live.com/start/PowerPoint.aspx , and sign in with your Microsoft account (including Outlook.com, Xbox Live, and Office 365 accounts). You’ll then see the Office template picker with many of the presentation templates from desktop PowerPoint—with your recently opened presentations on the left sidebar.

Select a template or open an existing presentation to open it in PowerPoint Online. With a similar design to recent versions of PowerPoint for Mac and Windows, you’ll find the core text and design tools on the main Home tab, options to add images and embedded videos and tables in the Insert tab, slide and template options in the Design tab, animations in the Transitions and Animations tab, and so on. If you can’t find the feature you need, type what you need in the Tell me what you want to do box to search through PowerPoint’s features and documentation.

Need to edit a picture or tweak a SmartArt graph? Select it, and a new Format tab will appear with additional tools as in desktop PowerPoint.

You may not need to look through the toolbars for tools, though. Select text in a slide and PowerPoint shows quick formatting options in a pop-over to change the font, color, and more. Or right-click on most other elements to find their quick editing options. You can then double-click on the toolbar to hide it and increase your workspace, if you’d like, relying on the popover tools to work faster.

Add a new slide: Ctrl + M or CMD + M

Move slides up or down: Ctrl + arrow or CMD + arrow

Add a comment: Alt + N

Go to next slide in Slideshow view: N

Go to previous slide in Slideshow view: P

Go to a specific slide in Slideshow view: G , then type slide number

Exit Slideshow view: Esc

How to Add Presentations to PowerPoint Online

PowerPoint Online is part of Microsoft’s OneDrive file storage. Open a PowerPoint file in OneDrive, and it’ll first show a preview with the option to edit it online.

But surprisingly, PowerPoint Online also works with Dropbox. That gives you another way to open your presentations online. You can save your presentations to either OneDrive or Dropbox, and then when you open PowerPoint Online, you can search through your presentations from both services. Either way, any change you make will automatically be saved to the original file.

The Dropbox integration only works for newer .pptx files. To open .ppt files, download them first, then upload them to PowerPoint Online or OneDrive. When you open them there, PowerPoint will automatically make a copy then convert the presentation to the new format so you can edit it online.

Or, if you have a PowerPoint file on your computer, open PowerPoint Online first, click the Upload a Presentation button, then select your presentation to upload it to OneDrive and open it for editing in PowerPoint Online at the same time.

How to Collaborate on PowerPoint Presentations

Want someone else to proofread your slides, or add their research to a team presentation? That’s easy in PowerPoint Online. From your presentation, click the Share button in the top right toolbar.

The default option is to email an invite link along with a message to your collaborators. You can choose to make the presentation editable or view only and can require a Microsoft account or not.

Or, you can copy a share link to send to anyone or share publicly online if you’d like. Select the Get a link tab to copy a link to your presentation—again, as a view-only presentation or with permission to edit. Here, if you make an editing link, anyone can tweak the presentation without signing into an account.

PowerPoint Online will show an icon beside the slide your collaborator is currently editing and will mark the section they’re working on in the same color. You can’t see the exact changes they make while they’re editing—changes take a few seconds to sync—so it’s best not to edit the same slide others are editing at the same time.

Want to chat with your collaborators? As long as everyone has a Skype account, you can open a Skype sidebar and talk with them in your PowerPoint presentation.

What’s Not In PowerPoint Online?

The core editing features are all here. You can add and edit text, photos, shapes, and SmartArt in PowerPoint online, add core transitions and animations to slides and elements, and present your presentation all from PowerPoint Online.

One of the main differences from PowerPoint’s desktop apps are the embedding options. In desktop versions of PowerPoint, you can embed video and audio from your computer, along with data from other Office apps and macros. In PowerPoint Online, you can embed online videos from YouTube—along with graphs and data from PowerBI and other add-ins in the Office Add-ins pane.

Animations are also more limited in PowerPoint Online. It includes only eight transitions, including Fade and Push , with animations that don’t require graphics acceleration. If you add a presentation that uses other animations from PowerPoint for Windows or Mac, you’ll need to select others or present without animations.

Fonts are another core difference. PowerPoint Online includes 18 fonts, including Arial, Comic Sans, Courier New, Garamond, Georgia, Rockwell, Tahoma, Times New Roman, and Verdana. You can’t install 3rd party fonts or choose fonts you have installed on your computer.

So, to make sure your PowerPoint presentations look great everywhere, stick with the fonts included with PowerPoint Online. That’s easy as they’re the only options in PowerPoint Online, but if you use another PowerPoint app, try using the Web fonts as they’re mainly fonts that work everywhere.

If you upload a presentation that uses a font not included in PowerPoint Online, you can still view the text in the correct font in PowerPoint Online on your computer or another computer with that font installed. If you don’t have the font installed, PowerPoint Online will replace that font with another similar font.

Beyond that, though, PowerPoint Online is surprisingly full-featured. It includes everything you need for making and showing presentations online—as long as you don’t need to use custom fonts, embed non-YouTube videos, or build advanced animations.

How to Present PowerPoint Presentations From Your Browser

Once you’ve finished creating your presentation, it’s time to present it. That’s as easy in PowerPoint Online as in the desktop apps. You can start the slideshow from the slide you’re currently editing via the Slide View button in the lower right-hand corner. Or, click the View tab and select to start the slideshow from the beginning or current slide.

PowerPoint Online will switch your browser to a full-screen preview mode. Click anywhere on the screen to go to the next slide, or tap your right and left arrows on your keyboard to navigate between slides. When finished, click again at the end of the presentation or press the Esc key to exit the slideshow and switch back to the windowed editor mode.

PowerPoint also includes controls on the lower left of the slideshow view, along with options in the right-click menu to switch slides or jump to a specific slide.

PowerPoint Online doesn’t include presenter view to show lecture notes on one screen while presenting your presentation on another—but there’s a workaround. While you’re giving your presentation full-screen, your browser with the original PowerPoint Online tab won’t show your slide content (Chrome hides the original window; Safari shows a Exit Full Screen placeholder). Instead, you can open a new tab or window and open your presentation there as well.

When you switch slides, move your mouse to your projection screen and click to advance—then move your mouse back to your laptop’s screen and select the next slide in your other PowerPoint Online window. Another option is to open your presentation in PowerPoint’s mobile apps and use your phone or tablet to view lecture notes while presenting from your laptop.

How to Convert PowerPoint Presentations Online

PowerPoint Online—unlike PowerPoint for Windows or Mac—can only open .pptx presentation files made with a newer version of PowerPoint. If you open an older .ppt file or a .odp presentation from another app, PowerPoint Online can convert the file to .pptx on the fly so you can edit the presentation.

But once you’ve opened the presentation, you can export it in 3 formats: PowerPoint, ODP (used with OpenOffice), or PDF. Click the File tab in the toolbar to open the core PowerPoint menu, select Download As , then choose the file format you want. PowerPoint Online will convert your presentation and save it to your computer so that you can share the original file with others.

The best option is to share the PowerPoint presentation directly in PowerPoint Online—but when you need a traditional presentation file, that’s a handy way to get it.

How to Save All Your Presentations to PowerPoint Online

There’s one trick to make PowerPoint Online the presentation app that’s always ready when you need it is: Save all your presentations to OneDrive or Dropbox. That way, whenever you need to present something, it’ll be a few clicks away inside PowerPoint Online.

If you already use OneDrive or Dropbox to sync your files, you’re halfway there. Save every new presentation there, every time. Whenever someone sends you a presentation, save it there also.

App automation tool Zapier can do that for you automatically. One of the most common ways to share presentations is through email—so Zapier can watch your Gmail or IMAP-powered email account for new presentation files. With Gmail, you can include a search to watch for presentation files. Use has:presentation to watch for any presentation—though note that this will also include Google Slides presentations which won’t work with PowerPoint Online. Or, use filename:pptx OR filename:ppt to watch for all PowerPoint attachments.

With IMAP email—or any other app where colleagues may send you presentations— add a Filter step to your Zap to watch the filename for .pptx or .ppt extensions.

Then, Zapier can save the presentation file to online storage to open and edit it in PowerPoint Online. The simplest is OneDrive since it’s PowerPoint Online’s core storage, though you could use Dropbox instead as it only takes a few extra clicks to open your presentations there.

You can save the presentation in any folder, and add a customized file name if you’d like. Then select the attachment from Gmail or your IMAP email and have Zapier copy that file to OneDrive or Dropbox. Next time you need to present something someone emailed you, don’t open your email app—instead, open PowerPoint Online and open the presentation there directly.

Ready to save any presentation you get emailed to PowerPoint Online? These Zaps will help you get started in a few clicks—remember to set up your search or filter to watch only for PowerPoint files:

Save new Gmail attachments to OneDrive

Save new email attachments to OneDrive

Save new attachments in Gmail to Dropbox

Back up new IMAP email attachments to Dropbox

That’s PowerPoint Online. It’s a handy way to tweak and present your presentation, even if you don’t have a copy of PowerPoint installed. And it just might be the new presentation app you need for a more focused, free way to make presentations anywhere.

A simple guide to slideshows

Learn what slideshows are, how they’re used, common features, and how to choose a slideshow maker. Get started creating your own slideshows today with Microsoft PowerPoint.

What is a slideshow?

What are slideshows used for.

Meetings and presentations

Slideshows are most frequently used to create professional presentations for business meetings, conferences, and educational purposes. A  slideshow program  allows people to organize content, include visuals, and enhance the overall impact of their message.

Visual storytelling

Because slideshows sequentially display engaging visuals, text, and other multimedia, they’re a strong way to tell a cohesive and compelling narrative from start to finish.

Content creation

Slideshows give content creators a versatile and efficient way to organize information, increase visual appeal, and communicate effectively across different contexts.

Photo and video sharing

Slideshow makers are popular for creating photo and video presentations, especially for events like weddings, birthdays, and vacations. People can add transitions, music, and captions to fully bring the photo-sharing experience to life.

Training and tutorials

Slideshows help break down complex information into digestible chunks with the support of visuals and text, making them ideal for instructional materials, tutorials, and training modules.

Collaborative projects

In collaborative settings, teams use slideshow makers to create joint presentations or reports. The best slideshow makers enable multiple contributors to add their content simultaneously, which helps ensure a cohesive and unified presentation.

What are the features of a slideshow creator?

Slideshow creators vary in what they offer but ideally include:

A library of templates, themes, and images.

If you’re not a designer, this feature is huge. Simply browse the options available in your slideshow maker library to create a polished, professionally designed presentation in a flash. Be sure to confirm that access to the library is free and the images are approved for unrestricted usage.

Audio and video compatibility.

Keeping your audience engaged is key to any successful slideshow presentation. To mix things up, being able to add a multimedia element—like a song or a video clip—will help people stay focused and interested.

Presentation tools.

Handy presenter tools go a long way toward making your slideshow experience seamless. For example, straightforward slide navigation, slideshow keyboard shortcuts, pen and highlighter markup, and adjustable resolution settings.

AI assistance.

With AI revolutionizing content creation, using a slideshow maker that has AI capabilities will enhance efficiency and innovation. Depending on the slideshow app you have, creating an entire slideshow could be as easy as a quick prompt, like “Make a presentation about the benefits of sustainable fashion that has 15 slides.” 

Animations.

Like audio and video, animations give your audience a bit of sensory surprise that can capture their attention. 

Slide transitions.

Add some pizzazz to how you change slides with visual effects like fading, wiping, and zooming. 

Screen recording.

Being able to record your screen in a slideshow maker is helpful when giving an instructional talk, software demonstration, and other types of presentations that require visual aids.

A place to put speaker notes.

Having somewhere to jot a few notes down will help remind you of everything you want to cover as you present.

Different viewing options.

Looking at different views—for example, a presenter view, an audience view, and a high-level view of slide order—is useful when organizing your slideshow’s structure and understanding and preparing for what you’ll see versus what your audience will see.

How do I choose the right slideshow maker?

When choosing a slideshow maker, keep the following questions in mind to make sure you get the most for your money:

Is it scalable with your business?

As your organization grows and changes, it’s important to have flexible technology that adapts to new needs. Having certain features—such as cloud-based collaboration, compatibility with other work apps, and a mobile app—will help ensure that no matter how your business changes, the slideshow maker is up to the task. This also applies to pricing plans. Consider choosing a slideshow app that has a subscription plan (so the software is always up to date), volume-based pricing, or enterprise-level pricing.

Does it have a variety of visual elements?

It’s pretty much a given that a slideshow maker will allow you to add images, but think outside the JPEG box—what other visual elements are available to you? Features like preset themes, free templates, SmartArt, a built-in clip art library, shape tools, background styles, 3D models, and charts and graphs provide diverse ways to switch up how a slideshow looks without relying solely on adding your own images.

Is it easy to use?

You could have the most feature-rich slideshow maker on the market, but if it isn’t easy to use, you probably won’t use it. Or you will, but you’ll be frustrated, waste valuable time, and have difficulty convincing people you work with to use it. As you research slideshow makers, look for videos that show the apps’ interfaces in action to help you decide if they’re intuitive and will have a shorter learning curve.

Does it have collaboration and sharing options?

Because making a slideshow is often a collaborative effort, it’s worthwhile to find a slideshow creator that was designed with this in mind. Pick one that offers editing controls and commenting, as well as the ability to work on a slideshow at the same time as someone else. Having a cloud-based slideshow maker will be key here. You’ll not only save yourself time but also keep things simple by not having multiple versions of the same slideshow.

OpenAI debuts GPT-4o ‘omni’ model now powering ChatGPT

OpenAI announced a new flagship generative AI model on Monday that they call GPT-4o — the “o” stands for “omni,” referring to the model’s ability to handle text, speech, and video. GPT-4o is set to roll out “iteratively” across the company’s developer and consumer-facing products over the next few weeks.

OpenAI CTO Mira Murati said that GPT-4o provides “GPT-4-level” intelligence but improves on GPT-4’s capabilities across multiple modalities and media.

“GPT-4o reasons across voice, text and vision,” Murati said during a streamed presentation at OpenAI’s offices in San Francisco on Monday. “And this is incredibly important, because we’re looking at the future of interaction between ourselves and machines.”

GPT-4 Turbo , OpenAI’s previous “leading “most advanced” model, was trained on a combination of images and text and could analyze images and text to accomplish tasks like extracting text from images or even describing the content of those images. But GPT-4o adds speech to the mix.

What does this enable? A variety of things. 

GPT-4o greatly improves the experience in OpenAI’s AI-powered chatbot, ChatGPT . The platform has long offered a voice mode that transcribes the chatbot’s responses using a text-to-speech model, but GPT-4o supercharges this, allowing users to interact with ChatGPT more like an assistant. 

For example, users can ask the GPT-4o-powered ChatGPT a question and interrupt ChatGPT while it’s answering. The model delivers “real-time” responsiveness, OpenAI says, and can even pick up on nuances in a user’s voice, in response generating voices in “a range of different emotive styles” (including singing). 

GPT-4o also upgrades ChatGPT’s vision capabilities. Given a photo — or a desktop screen — ChatGPT can now quickly answer related questions, from topics ranging from “What’s going on in this software code?” to “What brand of shirt is this person wearing?”

These features will evolve further in the future, Murati says. While today GPT-4o can look at a picture of a menu in a different language and translate it, in the future, the model could allow ChatGPT to, for instance, “watch” a live sports game and explain the rules to you.

“We know that these models are getting more and more complex, but we want the experience of interaction to actually become more natural, easy, and for you not to focus on the UI at all, but just focus on the collaboration with ChatGPT,” Murati said. “For the past couple of years, we’ve been very focused on improving the intelligence of these models … But this is the first time that we are really making a huge step forward when it comes to the ease of use.”

GPT-4o is more multilingual as well, OpenAI claims, with enhanced performance in around 50 languages. And in OpenAI’s API and Microsoft’s Azure OpenAI Service , GPT-4o is twice as fast as, half the price of and has higher rate limits than GPT-4 Turbo, the company says.

At present, voice isn’t a part of the GPT-4o API for all customers. OpenAI, citing the risk of misuse, says that it plans to first launch support for GPT-4o’s new audio capabilities to “a small group of trusted partners” in the coming weeks.

GPT-4o is available in the free tier of ChatGPT starting today and to subscribers to OpenAI’s premium ChatGPT Plus and Team plans with “5x higher” message limits. (OpenAI notes that ChatGPT will automatically switch to GPT-3.5 , an older and less capable model, when users hit the rate limit.) The improved ChatGPT voice experience underpinned by GPT-4o will arrive in alpha for Plus users in the next month or so, alongside enterprise-focused options .

In related news, OpenAI announced that it’s releasing a refreshed ChatGPT UI on the web with a new, “more conversational” home screen and message layout, and a desktop version of ChatGPT for macOS that lets users ask questions via a keyboard shortcut or take and discuss screenshots. ChatGPT Plus users will get access to the app first, starting today, and a Windows version will arrive later in the year.

Elsewhere, the GPT Store , OpenAI’s library of and creation tools for third-party chatbots built on its AI models, is now available to users of ChatGPT’s free tier. And free users can take advantage of ChatGPT features that were formerly paywalled, like a memory capability that allows ChatGPT to “remember” preferences for future interactions, upload files and photos, and search the web for answers to timely questions.

Metrics details

Scoping reviews and evidence maps are forms of evidence synthesis that aim to map the available literature on a topic and are well-suited to visual presentation of results. A range of data visualisation methods and interactive data visualisation tools exist that may make scoping reviews more useful to knowledge users. The aim of this study was to explore the use of data visualisation in a sample of recent scoping reviews and evidence maps on health topics, with a particular focus on interactive data visualisation.

Ovid MEDLINE ALL was searched for recent scoping reviews and evidence maps (June 2020-May 2021), and a sample of 300 papers that met basic selection criteria was taken. Data were extracted on the aim of each review and the use of data visualisation, including types of data visualisation used, variables presented and the use of interactivity. Descriptive data analysis was undertaken of the 238 reviews that aimed to map evidence.

Of the 238 scoping reviews or evidence maps in our analysis, around one-third (37.8%) included some form of data visualisation. Thirty-five different types of data visualisation were used across this sample, although most data visualisations identified were simple bar charts (standard, stacked or multi-set), pie charts or cross-tabulations (60.8%). Most data visualisations presented a single variable (64.4%) or two variables (26.1%). Almost a third of the reviews that used data visualisation did not use any colour (28.9%). Only two reviews presented interactive data visualisation, and few reported the software used to create visualisations.

Conclusions

Data visualisation is currently underused by scoping review authors. In particular, there is potential for much greater use of more innovative forms of data visualisation and interactive data visualisation. Where more innovative data visualisation is used, scoping reviews have made use of a wide range of different methods. Increased use of these more engaging visualisations may make scoping reviews more useful for a range of stakeholders.

Peer Review reports

Scoping reviews are “a type of evidence synthesis that aims to systematically identify and map the breadth of evidence available on a particular topic, field, concept, or issue” ([ 1 ], p. 950). While they include some of the same steps as a systematic review, such as systematic searches and the use of predetermined eligibility criteria, scoping reviews often address broader research questions and do not typically involve the quality appraisal of studies or synthesis of data [ 2 ]. Reasons for conducting a scoping review include the following: to map types of evidence available, to explore research design and conduct, to clarify concepts or definitions and to map characteristics or factors related to a concept [ 3 ]. Scoping reviews can also be undertaken to inform a future systematic review (e.g. to assure authors there will be adequate studies) or to identify knowledge gaps [ 3 ]. Other evidence synthesis approaches with similar aims have been described as evidence maps, mapping reviews or systematic maps [ 4 ]. While this terminology is used inconsistently, evidence maps can be used to identify evidence gaps and present them in a user-friendly (and often visual) way [ 5 ].

Scoping reviews are often targeted to an audience of healthcare professionals or policy-makers [ 6 ], suggesting that it is important to present results in a user-friendly and informative way. Until recently, there was little guidance on how to present the findings of scoping reviews. In recent literature, there has been some discussion of the importance of clearly presenting data for the intended audience of a scoping review, with creative and innovative use of visual methods if appropriate [ 7 , 8 , 9 ]. Lockwood et al. suggest that innovative visual presentation should be considered over dense sections of text or long tables in many cases [ 8 ]. Khalil et al. suggest that inspiration could be drawn from the field of data visualisation [ 7 ]. JBI guidance on scoping reviews recommends that reviewers carefully consider the best format for presenting data at the protocol development stage and provides a number of examples of possible methods [ 10 ].

Interactive resources are another option for presentation in scoping reviews [ 9 ]. Researchers without the relevant programming skills can now use several online platforms (such as Tableau [ 11 ] and Flourish [ 12 ]) to create interactive data visualisations. The benefits of using interactive visualisation in research include the ability to easily present more than two variables [ 13 ] and increased engagement of users [ 14 ]. Unlike static graphs, interactive visualisations can allow users to view hierarchical data at different levels, exploring both the “big picture” and looking in more detail ([ 15 ], p. 291). Interactive visualizations are often targeted at practitioners and decision-makers [ 13 ], and there is some evidence from qualitative research that they are valued by policy-makers [ 16 , 17 , 18 ].

Given their focus on mapping evidence, we believe that scoping reviews are particularly well-suited to visually presenting data and the use of interactive data visualisation tools. However, it is unknown how many recent scoping reviews visually map data or which types of data visualisation are used. The aim of this study was to explore the use of data visualisation methods in a large sample of recent scoping reviews and evidence maps on health topics. In particular, we were interested in the extent to which these forms of synthesis use any form of interactive data visualisation.

This study was a cross-sectional analysis of studies labelled as scoping reviews or evidence maps (or synonyms of these terms) in the title or abstract.

The search strategy was developed with help from an information specialist. Ovid MEDLINE® ALL was searched in June 2021 for studies added to the database in the previous 12 months. The search was limited to English language studies only.

The search strategy was as follows:

Ovid MEDLINE(R) ALL

The search returned 3686 records. Records were de-duplicated in EndNote 20 software, leaving 3627 unique records.

A sample of these reviews was taken by screening the search results against basic selection criteria (Table 1 ). These criteria were piloted and refined after discussion between the two researchers. A single researcher (E.S.) screened the records in EPPI-Reviewer Web software using the machine-learning priority screening function. Where a second opinion was needed, decisions were checked by a second researcher (M.R.).

Our initial plan for sampling, informed by pilot searching, was to screen and data extract records in batches of 50 included reviews at a time. We planned to stop screening when a batch of 50 reviews had been extracted that included no new types of data visualisation or after screening time had reached 2 days. However, once data extraction was underway, we found the sample to be richer in terms of data visualisation than anticipated. After the inclusion of 300 reviews, we took the decision to end screening in order to ensure the study was manageable.

Data extraction

A data extraction form was developed in EPPI-Reviewer Web, piloted on 50 reviews and refined. Data were extracted by one researcher (E. S. or M. R.), with a second researcher (M. R. or E. S.) providing a second opinion when needed. The data items extracted were as follows: type of review (term used by authors), aim of review (mapping evidence vs. answering specific question vs. borderline), number of visualisations (if any), types of data visualisation used, variables/domains presented by each visualisation type, interactivity, use of colour and any software requirements.

When categorising review aims, we considered “mapping evidence” to incorporate all of the six purposes for conducting a scoping review proposed by Munn et al. [ 3 ]. Reviews were categorised as “answering a specific question” if they aimed to synthesise study findings to answer a particular question, for example on effectiveness of an intervention. We were inclusive with our definition of “mapping evidence” and included reviews with mixed aims in this category. However, some reviews were difficult to categorise (for example where aims were unclear or the stated aims did not match the actual focus of the paper) and were considered to be “borderline”. It became clear that a proportion of identified records that described themselves as “scoping” or “mapping” reviews were in fact pseudo-systematic reviews that failed to undertake key systematic review processes. Such reviews attempted to integrate the findings of included studies rather than map the evidence, and so reviews categorised as “answering a specific question” were excluded from the main analysis. Data visualisation methods for meta-analyses have been explored previously [ 19 ]. Figure  1 shows the flow of records from search results to final analysis sample.

Flow diagram of the sampling process

Data visualisation was defined as any graph or diagram that presented results data, including tables with a visual mapping element, such as cross-tabulations and heat maps. However, tables which displayed data at a study level (e.g. tables summarising key characteristics of each included study) were not included, even if they used symbols, shading or colour. Flow diagrams showing the study selection process were also excluded. Data visualisations in appendices or supplementary information were included, as well as any in publicly available dissemination products (e.g. visualisations hosted online) if mentioned in papers.

The typology used to categorise data visualisation methods was based on an existing online catalogue [ 20 ]. Specific types of data visualisation were categorised in five broad categories: graphs, diagrams, tables, maps/geographical and other. If a data visualisation appeared in our sample that did not feature in the original catalogue, we checked a second online catalogue [ 21 ] for an appropriate term, followed by wider Internet searches. These additional visualisation methods were added to the appropriate section of the typology. The final typology can be found in Additional file 1 .

We conducted descriptive data analysis in Microsoft Excel 2019 and present frequencies and percentages. Where appropriate, data are presented using graphs or other data visualisations created using Flourish. We also link to interactive versions of some of these visualisations.

Almost all of the 300 reviews in the total sample were labelled by review authors as “scoping reviews” ( n  = 293, 97.7%). There were also four “mapping reviews”, one “scoping study”, one “evidence mapping” and one that was described as a “scoping review and evidence map”. Included reviews were all published in 2020 or 2021, with the exception of one review published in 2018. Just over one-third of these reviews ( n  = 105, 35.0%) included some form of data visualisation. However, we excluded 62 reviews that did not focus on mapping evidence from the following analysis (see “ Methods ” section). Of the 238 remaining reviews (that either clearly aimed to map evidence or were judged to be “borderline”), 90 reviews (37.8%) included at least one data visualisation. The references for these reviews can be found in Additional file 2 .

Number of visualisations

Thirty-six (40.0%) of these 90 reviews included just one example of data visualisation (Fig.  2 ). Less than a third ( n  = 28, 31.1%) included three or more visualisations. The greatest number of data visualisations in one review was 17 (all bar or pie charts). In total, 222 individual data visualisations were identified across the sample of 238 reviews.

Number of data visualisations per review

Categories of data visualisation

Graphs were the most frequently used category of data visualisation in the sample. Over half of the reviews with data visualisation included at least one graph ( n  = 59, 65.6%). The least frequently used category was maps, with 15.6% ( n  = 14) of these reviews including a map.

Of the total number of 222 individual data visualisations, 102 were graphs (45.9%), 34 were tables (15.3%), 23 were diagrams (10.4%), 15 were maps (6.8%) and 48 were classified as “other” in the typology (21.6%).

Types of data visualisation

All of the types of data visualisation identified in our sample are reported in Table 2 . In total, 35 different types were used across the sample of reviews.

The most frequently used data visualisation type was a bar chart. Of 222 total data visualisations, 78 (35.1%) were a variation on a bar chart (either standard bar chart, stacked bar chart or multi-set bar chart). There were also 33 pie charts (14.9% of data visualisations) and 24 cross-tabulations (10.8% of data visualisations). In total, these five types of data visualisation accounted for 60.8% ( n  = 135) of all data visualisations. Figure  3 shows the frequency of each data visualisation category and type; an interactive online version of this treemap is also available ( https://public.flourish.studio/visualisation/9396133/ ). Figure  4 shows how users can further explore the data using the interactive treemap.

Data presented

Around two-thirds of data visualisations in the sample presented a single variable ( n  = 143, 64.4%). The most frequently presented single variables were themes ( n  = 22, 9.9% of data visualisations), population ( n  = 21, 9.5%), country or region ( n  = 21, 9.5%) and year ( n  = 20, 9.0%). There were 58 visualisations (26.1%) that presented two different variables. The remaining 21 data visualisations (9.5%) presented three or more variables. Figure  5 shows the variables presented by each different type of data visualisation (an interactive version of this figure is available online).

Variables presented by each data visualisation type. Darker cells indicate a larger number of reviews. An interactive version of this heat map is available online: https://public.flourish.studio/visualisation/10632665/ . Users can hover over each cell to see the number of data visualisations for that combination of data visualisation type and variable. The unit of this heat map is the individual data visualisation, so multiple data visualisations within a single scoping review are represented in this map. Created with flourish.studio ( https://flourish.studio )

Most reviews presented at least one data visualisation in colour ( n  = 64, 71.1%). However, almost a third ( n  = 26, 28.9%) used only black and white or greyscale.

Interactivity

Only two of the reviews included data visualisations with any level of interactivity. One scoping review on music and serious mental illness [ 22 ] linked to an interactive bubble chart hosted online on Tableau. Functionality included the ability to filter the studies displayed by various attributes.

The other review was an example of evidence mapping from the environmental health field [ 23 ]. All four of the data visualisations included in the paper were available in an interactive format hosted either by the review management software or on Tableau. The interactive versions linked to the relevant references so users could directly explore the evidence base. This was the only review that provided this feature.

Software requirements

Nine reviews clearly reported the software used to create data visualisations. Three reviews used Tableau (one of them also used review management software as discussed above) [ 22 , 23 , 24 ]. Two reviews generated maps using ArcGIS [ 25 ] or ArcMap [ 26 ]. One review used Leximancer for a lexical analysis [ 27 ]. One review undertook a bibliometric analysis using VOSviewer [ 28 ], and another explored citation patterns using CitNetExplorer [ 29 ]. Other reviews used Excel [ 30 ] or R [ 26 ].

To our knowledge, this is the first systematic and in-depth exploration of the use of data visualisation techniques in scoping reviews. Our findings suggest that the majority of scoping reviews do not use any data visualisation at all, and, in particular, more innovative examples of data visualisation are rare. Around 60% of data visualisations in our sample were simple bar charts, pie charts or cross-tabulations. There appears to be very limited use of interactive online visualisation, despite the potential this has for communicating results to a range of stakeholders. While it is not always appropriate to use data visualisation (or a simple bar chart may be the most user-friendly way of presenting the data), these findings suggest that data visualisation is being underused in scoping reviews. In a large minority of reviews, visualisations were not published in colour, potentially limiting how user-friendly and attractive papers are to decision-makers and other stakeholders. Also, very few reviews clearly reported the software used to create data visualisations. However, 35 different types of data visualisation were used across the sample, highlighting the wide range of methods that are potentially available to scoping review authors.

Our results build on the limited research that has previously been undertaken in this area. Two previous publications also found limited use of graphs in scoping reviews. Results were “mapped graphically” in 29% of scoping reviews in any field in one 2014 publication [ 31 ] and 17% of healthcare scoping reviews in a 2016 article [ 6 ]. Our results suggest that the use of data visualisation has increased somewhat since these reviews were conducted. Scoping review methods have also evolved in the last 10 years; formal guidance on scoping review conduct was published in 2014 [ 32 ], and an extension of the PRISMA checklist for scoping reviews was published in 2018 [ 33 ]. It is possible that an overall increase in use of data visualisation reflects increased quality of published scoping reviews. There is also some literature supporting our findings on the wide range of data visualisation methods that are used in evidence synthesis. An investigation of methods to identify, prioritise or display health research gaps (25/139 included studies were scoping reviews; 6/139 were evidence maps) identified 14 different methods used to display gaps or priorities, with half being “more advanced” (e.g. treemaps, radial bar plots) ([ 34 ], p. 107). A review of data visualisation methods used in papers reporting meta-analyses found over 200 different ways of displaying data [ 19 ].

Only two reviews in our sample used interactive data visualisation, and one of these was an example of systematic evidence mapping from the environmental health field rather than a scoping review (in environmental health, systematic evidence mapping explicitly involves producing a searchable database [ 35 ]). A scoping review of papers on the use of interactive data visualisation in population health or health services research found a range of examples but still limited use overall [ 13 ]. For example, the authors noted the currently underdeveloped potential for using interactive visualisation in research on health inequalities. It is possible that the use of interactive data visualisation in academic papers is restricted by academic publishing requirements; for example, it is currently difficult to incorporate an interactive figure into a journal article without linking to an external host or platform. However, we believe that there is a lot of potential to add value to future scoping reviews by using interactive data visualisation software. Few reviews in our sample presented three or more variables in a single visualisation, something which can easily be achieved using interactive data visualisation tools. We have previously used EPPI-Mapper [ 36 ] to present results of a scoping review of systematic reviews on behaviour change in disadvantaged groups, with links to the maps provided in the paper [ 37 ]. These interactive maps allowed policy-makers to explore the evidence on different behaviours and disadvantaged groups and access full publications of the included studies directly from the map.

We acknowledge there are barriers to use for some of the data visualisation software available. EPPI-Mapper and some of the software used by reviews in our sample incur a cost. Some software requires a certain level of knowledge and skill in its use. However numerous online free data visualisation tools and resources exist. We have used Flourish to present data for this review, a basic version of which is currently freely available and easy to use. Previous health research has been found to have used a range of different interactive data visualisation software, much of which does not required advanced knowledge or skills to use [ 13 ].

There are likely to be other barriers to the use of data visualisation in scoping reviews. Journal guidelines and policies may present barriers for using innovative data visualisation. For example, some journals charge a fee for publication of figures in colour. As previously mentioned, there are limited options for incorporating interactive data visualisation into journal articles. Authors may also be unaware of the data visualisation methods and tools that are available. Producing data visualisations can be time-consuming, particularly if authors lack experience and skills in this. It is possible that many authors prioritise speed of publication over spending time producing innovative data visualisations, particularly in a context where there is pressure to achieve publications.

Limitations

A limitation of this study was that we did not assess how appropriate the use of data visualisation was in our sample as this would have been highly subjective. Simple descriptive or tabular presentation of results may be the most appropriate approach for some scoping review objectives [ 7 , 8 , 10 ], and the scoping review literature cautions against “over-using” different visual presentation methods [ 7 , 8 ]. It cannot be assumed that all of the reviews that did not include data visualisation should have done so. Likewise, we do not know how many reviews used methods of data visualisation that were not well suited to their data.

We initially relied on authors’ own use of the term “scoping review” (or equivalent) to sample reviews but identified a relatively large number of papers labelled as scoping reviews that did not meet the basic definition, despite the availability of guidance and reporting guidelines [ 10 , 33 ]. It has previously been noted that scoping reviews may be undertaken inappropriately because they are seen as “easier” to conduct than a systematic review ([ 3 ], p.6), and that reviews are often labelled as “scoping reviews” while not appearing to follow any established framework or guidance [ 2 ]. We therefore took the decision to remove these reviews from our main analysis. However, decisions on how to classify review aims were subjective, and we did include some reviews that were of borderline relevance.

A further limitation is that this was a sample of published reviews, rather than a comprehensive systematic scoping review as have previously been undertaken [ 6 , 31 ]. The number of scoping reviews that are published has increased rapidly, and this would now be difficult to undertake. As this was a sample, not all relevant scoping reviews or evidence maps that would have met our criteria were included. We used machine learning to screen our search results for pragmatic reasons (to reduce screening time), but we do not see any reason that our sample would not be broadly reflective of the wider literature.

Data visualisation, and in particular more innovative examples of it, is currently underused in published scoping reviews on health topics. The examples that we have found highlight the wide range of methods that scoping review authors could draw upon to present their data in an engaging way. In particular, we believe that interactive data visualisation has significant potential for mapping the available literature on a topic. Appropriate use of data visualisation may increase the usefulness, and thus uptake, of scoping reviews as a way of identifying existing evidence or research gaps by decision-makers, researchers and commissioners of research. We recommend that scoping review authors explore the extensive free resources and online tools available for data visualisation. However, we also think that it would be useful for publishers to explore allowing easier integration of interactive tools into academic publishing, given the fact that papers are now predominantly accessed online. Future research may be helpful to explore which methods are particularly useful to scoping review users.

What is Presenter view?

Get an overview of Presenter view and learn what's required to use it in PowerPoint.

Ensure that the computer you are using for your presentation supports the use of multiple monitors. If the computer has multiple input ports, such as DVI, VGA, HDMI, ir DisplayPort, it should support multiple monitors. Most modern desktop computers have multiple monitor support built in; if not, you'll need two video cards.

Overview of Presenter view

Presenter view lets you view your presentation with your speaker notes on one computer (your laptop, for example), while the audience views the notes-free presentation on a different monitor.

Note:  PowerPoint only supports the use of two monitors for a presentation. However, you can configure to run a presentation on three or more monitors that are connected to one computer. Check your computer manufacturer’s website for up-to-date information about multiple monitor support for your computer.

Presenter view offers the following tools to make it easier for you to present information:

You can use thumbnails to select slides out of sequence and create a customized presentation for your audience.

Speaker's notes are shown in large, clear type so that you can use them as a script for your presentation.

You can darken or lighten the screen during your presentation and then resume where you left off. For example, you might not want to display the slide content during a break or a question and answer period.

In Presenter view, icons and buttons are large enough to navigate easily, even when you are using an unfamiliar keyboard or mouse. The following illustration shows the various tools that are available to you from Presenter view.

1. The slide number (for example, slide 1 of an 8-slide presentation)

2. The slide you are currently showing to the audience

3. The speaker's notes, which you can use as a script for your presentation

4. Click to go to the previous slide

5. Click to go to the next slide

6. The elapsed time of your presentation, in hours and minutes

7. Click to view thumbnails of all slides in your presentation

8. The pen, laser pointer, or highlighter tool

How to Watch the 2024 Met Gala Livestream Replay

By Christian Allaire

The 2024 Met Gala took place last night, on Monday, May 6. For the fourth year in a row, Vogue hosted the night’s exclusive livestream, where all of the action from the red carpet unfolded in real time.

This year, the Vogue Met Gala livestream was hosted by actor Gwendoline Christie, producer and actor La La Anthony, and model Ashley Graham. Multihyphenate Emma Chamberlain returned as Vogue ’s special correspondent to interview some of the biggest stars on the carpet. If you missed it last night, you can still catch up on all of the fashion fun—rewatch the livestream now to see all the A-listers as they arrived in style.

Meanwhile, this year’s theme—“ Sleeping Beauties: Reawakening Fashion ”—celebrated the Costume Institute’s new exhibition of the same name. The presentation will feature approximately 250 items drawn from the museum’s permanent collection, some rarely seen in public before, displayed in entirely new ways. Of course, the Met Gala’s star-studded red carpet on the first Monday in May cannot be missed either.

Below, everything to know about the 2024 Met Gala livestream, from how (and where) to rewatch the red carpet to what the night’s dress code and themes entail.

Where can I watch the livestream?

The 2024 Met Gala livestream was hosted exclusively by Vogue and broadcast live across its digital platforms as well as TikTok and YouTube . You can also rewatch the livestream within this very post and catch up on Vogue ’s by-the-minute live updates from the 2024 Met Gala here.

What time does the livestream start?

The Met Gala red-carpet livestream took place on Monday, May 6, starting at 6 p.m. ET/3 p.m. PST. If you missed it, you can watch the replay on this page!

Who’s hosting the livestream?

This year the Met Gala livestream was hosted by actor Gwendoline Christie, producer and actor La La Anthony, and model Ashley Graham. Multihyphenate Emma Chamberlain also returned as Vogue ’s special correspondent to interview some of the biggest stars on the carpet.

What’s this year’s Met Gala theme?

The 2024 Met Gala celebrated the opening of the Costume Institute’s new spring exhibition, “Sleeping Beauties: Reawakening Fashion.” The exhibition—which will be on view at The Metropolitan Museum of Art from May 10 to September 2 this year—will spotlight 250 items drawn from the Costume Institute’s permanent collection, including some very rarely seen in public before. All works will be displayed in entirely new ways, utilizing elements such as video animation, CGI, AI, and more.

Every year the Met Gala provides the Costume Institute with its primary source of funding for exhibitions, publications, acquisitions, operations, and capital improvements.

Is there a dress code?

The dress code for the 2024 Met Gala was The Garden of Time, which takes inspiration from a short story of the same title written by J.G. Ballard in 1962.

Who are the co-chairs this year?

Zendaya, Jennifer Lopez, Chris Hemsworth, Bad Bunny, and Vogue ’s Anna Wintour served as the evening’s co-chairs . Honorary chairs for the evening, meanwhile, were Loewe creative director Jonathan Anderson and TikTok CEO Shou Chew.
