mxGraph is a fully client side JavaScript diagramming library that uses SVG and HTML for rendering. [draw.io](https://www.draw.io) is an example that extends the functionality of this library. The [sources to draw.io](https://github.com/jgraph/draw.io) are also available.
If you want to build something like draw.io, [GraphEditor](https://jgraph.github.io/mxgraph/javascript/examples/grapheditor/www/index.html) is the best example to use as a base.
mxGraph supports IE 11, Chrome 32+, Firefox 38+, Safari 7.1.x, 8.0.x, 9.1.x and 10.0.x, Opera 20+, Native Android browser 5.1.x+, the default browser in the current and previous major iOS versions (e.g. 10.x and 9.x) and Edge 23+.
In the root folder there is an index.html file that contains links to all resources. You can view the documentation online on the [Github pages branch](https://jgraph.github.io/mxgraph/). The key resources are the JavaScript user manual, the JavaScript examples and the JavaScript API specificiation.

We created mxGraph in 2005 as a commercial project and it ran through to 2016 that way. Our USP was the support for non-SVG browsers, when that advantage expired we moved onto commercial activity around draw.io. mxGraph is pretty much feature complete, production tested in many large enterprises and stable for many years. We actively fix bugs and make minor improvements since it comprises the base of our draw.io stack.
