[Feature request] Fill pattern for Choropleth Mapbox

[ReichYang]

Hi. I wonder if plotly's choropleth can support not only filling the polygon with colors but also different patterns/hatchings.

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

Hi, is there any updates? I find that "fill pattern“ is supported in scatter, but I can't find how to modify the marker fill pattern for choropleth.

@gvwilson Sorry to bother you, but could you please reopen this issue?
https://github.com/plotly/plotly.py/blob/c54a2bdf1655caaaa3b7b71fbfc38a5584767bd5/plotly/graph_objs/choropleth/_marker.py
It seems that pattern is not a valid prop for choropleth markers

Hi @leakyH - I'll reopen the issue, but realistically we're not going to get to this any time soon. If you would like to create a PR, I can prioritize review. Thanks - @gvwilson
