This a Qt widget that embeds a rich and powerful graph drawing tool using JavaScript's mxGraph library.
It makes use of Qt web view features to make this possible. Since current Qt version supported (<= 5.6) is still using WebKit as its web browser engine, all of its limitations apply when developing new embedded web features.
Due to changes in mxgraph we are currently only supporting an old version of mxgraph (3.7.5).
