mxGraph
mxGraph is a fully client side JavaScript diagramming library - jgraph/mxgraph
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.
Over time you can expect this codebase will break features against new browser releases, it’s not advised to start new projects against this codebase for that reason.

Development on mxGraph has now stopped, this repo is effectively end of life.
