Using Python & Tkinter to interact with a Graphviz Digraph

[TrevorS]

Hi, I’ve been working on a Python code to automate node colours on a directed graph to track progress on project tasks. However, I’d like to evolve it to the point where I can select nodes and edges to edit (or add or delete) direct on the screen with mouse/keyboard interaction.

I was looking at Tkinter canvas but I haven’t found a way to import a dot graph to dispaly in the canvas let alone click on nodes etc. to identify them. Can someone point me in the right direction with either a few commands to research or a tutorial or three?

Failing that, is there an alternative to Tkinter canvas that might work as a screen interface? I’m running Windows 10.Thanks in adcance.
