@empet by chance do you know the link of the gml data mentioned in the following link. The source data link is moved and no longer be available and can you let me, know where I can find it?
@DennisZ
You can download it from github. The code was written six years ago with Python 2 and an early Plotly version. Iβm not sure if it still works or not.
This is the code. It is 6 yo, too, but from time to time I updated it after some plotly releases. A user collected the code from notebook into a few functions, and the link to the corresponding github gist was posted here. Search, pls, this forum with βchord diagramβ and itβs possible to find that link.
