This is an excellent library! I only wish it had react-native support.
I've worked on a few prototype react directed acyclical diagram libraries. jsplumb-react, react-yad, and recently @lincle.
@lincle is my most recent and first attempt at supporting react-native. I tried leveraging existing interactive libraries. I was also inspired by react-flow's minimap. It is still a prototype and needs documentation but works well. I'm realizing now the demo isn't working but the demo source should hopefully give an example of how to use it.
With expo DOM components it’s easy to just use this library and expo will wrap it in a webview. Then you can easily integrate it into a RN app.
