Feature Request: Add Multi-category Support for Gantt Chart

[mtwichan]

It would be great if: plotly/plotly.js#3300 (Multi-Category) supported https://plot.ly/python/gantt/ (Plotly Gantt Chart). Currently at this moment it is unsupported.

Thanks for the suggestion @matthewchan15

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
