The scatter GL is documented here: https://plotly.com/python/line-and-scatter/
I check back every few months to see if Gantt GL has been implemented, but it has been over a year now, so I thought I’d request it here.
Gantt charts are amazing for one of our use cases, but rendering them with more than 25K lines becomes cumbersome. It would be truly incredible to have the speed and performance demonstrated by ScatterGL with Gantt charts… so if some developer out there is listening, this would be awesome if you could implement this!!
