px.sankey

[nicolaskruchten]

We need a px.sankey and I think modelling it after the path flavour of px.sunburst introduced in #2006 is a great starting point! By default it would be always-branching, but we could add a merge_nodes=True option which could collapse nodes or something

for 4.6 I guess?

Hehe yes :)

Would love to pair on this one if this is already being worked. If it's helpful, I made a PyPI package to automate wrangling of dataframes for sankey charts with what I thought might be helpful assumptions/defaults. Maybe it sparks some good discussion on defaults, and I'm sure it could be modeled similarly to path in px.sunburst.

Here's a link to the main logic I was using: https://github.com/MCBoarder289/sankeyfy/blob/master/sankeyfy/__init__.py

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for several years, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Thanks for your help - @gvwilson
