2020.'s open source diagramming is moving to

Popular open source diagramming web app is migrating away from its iconic .io domain name to in order to improve security and ethics. The main impetus for the move is a security issue inherent to .io top-level domains that the administrator behind issuing said domains has provided zero communication addressing. This complete lack of communication has caused the development team to lose their trust of the .io TLD administrator. The transition from to will be slow and last through all of 2020. The domain name will continue to serve the diagramming web application without any redirects until the transition has fully completed.

2019. Google Drawings can now be embedded into Google Docs and easily updated

Google Drawings will soon feature improved Google Docs integration by allowing a direct and updating embed. At the moment, users have to manually create a new drawing from the Google Docs insert menu. A separate window opens to allow users to work on a Google Drawings file, with the ability to insert once they are finished editing. With the new integration, heading to “Drawing” in the “Insert” menu will reveal a new “From Drive” option that opens up a Drive file picker to select an existing Drawings file. Once embedded, the drawing is linked to that doc, with users able to update it if changes are made to the source. You can also unlink the work to make further customizations and edits that won’t be reflected.

To make documenting their infrastructure and offerings easy, Amazon's brilliant designers have created icons to represent every service they provide.

2017. Microsoft launches Visio Online editor

Microsoft Visio was the first popular tool for building schemes and diagrams, designing software and site interfaces. But then a lot of online alternatives (like Gliffy, OmniGiraffe) appeared with collaboravite features, and most users forgot about the heavy Visio. For some reason Microsoft didn't release the online version of Visio together with other Office editors (Word, Excel...). Then, some years later (in 2016) the company launched just Visio Online viewer. And only now Visio Online becomes full-featured app that allows to build and edit diagrams in browser and organize teamwork on them. It costs $5/month per user. The free Visio Onilne viewer is available in almost all Office 365 plans.

2017. OmniGraffle brings its Mac-features to iOS

OmniGraffle released new version for iOS. It adopts the paneled design found on the Mac, which should make fans of that version feel right at home with the update. Navigation and object inspection are handled by the new panels. On an iPad or in landscape mode on a Plus-size iPhone, the panels slide in from the sides of the screen. On smaller iPhones or portrait mode on a Plus-sized iPhone, the panels slide up from the bottom of the screen. The app also brings the iOS version in line with the core functionality of the macOS version including features like artboards. It’s nice that OmniGraffle is Universal because it can be handy to make quick edits on your iPhone if that’s all you have, but using OmniGraffle is a much better experience on the largest iPad screen you can afford.

Like the previous version, the public release is free and aimed primarily at allowing users of the full Visio for Windows application to view and collaborate on Visio diagrams on any platform that can run a web browser.

There is a basic template and then there is another template for cross-functional flowcharts providing a sample mapping table to populate with diagram metadata. The table includes predefined columns for process step number, description, dependencies, owner, function, phase and more. Users can also customize the table with their own columns to meet specific business requirements.

2017. OmniGraffle adds Artboards to presentation mode

OmniGraffle 7.3 added the ability to present your artboards in Presentation Mode. OmniGraffle’s Presentation Mode has always allowed you to treat each canvas like a slide to showcase them full screen—now you can present individual artboards, too. Presenting your individual designs, isolated from your busy canvas with artboards, only show your content within each boundary shape and above it in your layer hierarchy. To start a presentation, use the item in the View menu. When presenting, the up and down arrow keys move between canvases while the left and right arrow keys move between artboards.  To help with navigation, we’ve simplified the sidebar to minimize accidental clicks—just move the cursor all the way to the left.

Vector drawing and diagraming tool OmniGraffle for Mac gets a big update. With version 7, OmniGraffle supports an infinitely expandable canvas.

OmniGraffle 7 plays better with other graphics apps. The app previously added support for exporting your work as an SVG file, but now, you can also import SVG graphics, which means OmniGraffle can become part of whole new workflows. Pro users can also take advantage of artboards in OmniGraffle 7.

2016. Microsoft is bringing Visio to Android and Windows Phone

Just a few weeks after Microsoft started testing Visio for iOS, the company announced that the Visio app will be coming to Android and Windows phones sometime soon. Unfortunately though, there aren’t many details about the app itself. For example, Microsoft is yet to share when the app will be available for download on Windows Phone or even Android. However, what we do know is that the Android and Windows Phone app will have feature parity with the iOS app which is pretty good to know. Visio is an app mostly used for diagrams and charts. Despite its utility, it’s not a very popular app, and many users don’t even know it exists. Visio simplifies complex information through simple, easy-to-understand diagrams, and it a very useful tool for business professionals.

2014. Grapholite - MS Visio alternative for Android

Microsoft so appreciates its diagram-drawing application Visio, that sells it separately from the Office 365 for as high as 18/month/user. The most popular alternatives to MS Visio - is a great SaaS service Gliffy, which costs $5/month and free Google Drawings, which, however, is only suitable for simple diagrams.

This is online service + desktop app. Few days ago they also released the first full-featured Android app for drawing business graphics on tablets. Now, with the help of your finger you can draw quite complex and beautiful charts.

2013. OmniGraffle Pro 6 gets a facelift

OmniGraffle 6 gets a modernized engine to enjoy and some interface changes to, well, get used to. Using version 6 is not dramatically different from OmniGraffle Pro’s previous incarnation. All of the tools and controls have been redrawn with an eye to making their functions easily understood at a glance. OmniGraffle Pro’s new Resource Browser offers various templates and shape collections called Stencils for creating these documents. If, say, you’re working on a new floor plan for an office, you can choose from the Resource Browser a space-planning template where 1 inch equals 1 foot.

2013. Gliffy moves to HTML5

Web-based diagram creation tool Gliffy has been rewritten in HTML5, allowing its developer to add a slew of new features, including support for Microsoft Visio as well as Google Drive cloud storage. The shift from Flash to HTML5 was "highly risky," but something that the developers have seen as necessary. Gliffy is now actually live in both Flash as well as HTML5, but given the large number of HTML5-compliant browsers available, the Flash version is quickly losing relevance. The new release also adds features such as the ability to drag and drop images, and coherent themes that can be extended across a diagram or flowchart as a whole.

2010. Google Docs adds Visio killer, collaborative editing in Google Wave style

When Microsoft demoed the Office Web Apps, we noted that nobody knows what will Google Docs look like when Office 2010 finally launch. MS Office Web will appear at least in 2 months and this question is still relevant. While Microsoft is fixing bugs in its web office, Google is constantly improving Docs. The new version of Google Docs features the significantly improved collaborative editing technology. It has a sidebar, which displays a list of users who are editing or viewing the document right now. On the same panel is chat. Each user is assigned a color and you can watch in real-time how your co-workers edit document (like in Google Wave or Etherpad). Moreover, this technology works in text documents and spreadsheets, and in the new Google Drawings.
