I have to say that I'm looking for something interactive, which is equivalent to what Nevron offers in the .NET Diagram product, where the user can create nodes, interact with them by dragging and dropping them, etc. I know that GraphViz, but as far as I know, it is static and just displays a graph / chart, there is no interaction with it.
I have a bad feeling that in a cross-platform world for Python or any other script language there is nothing as rich as this, but maybe I missed it.
