Create diagrams with the help of MJS Diagram

This application is based on the MJS Diagram library and you can use it to create, view, and share flowcharts, org charts, network diagrams, mind maps and more.

Everything is created and stored in your browser and none of your content is sent back to our or any other servers. This means that your diagrams are exclussively yours but it also means that when you open this page on another machine (or just another browser or profile on the same device) you won't see your previously created diagrams. You can work around this by exporting your diagrams on this device and, for example, saving them in your cloud storage service of choice (Dropbox, Google Drive, OneDrive, iCloud, etc.)

In addition to being a useful diagramming tool, this app is also a demo for the MJS Diagram library. The source code is available on GitHub under the MIT license. You can take this app and learn how to build real-world MJS Diagram implementations, or just extend it to fit your specific needs.
