Hi! I can't seem to find the example charts and data behind the examples in the gallery.
What I really want to see is how the French District map <https://apache-superset.readthedocs.io/en/0.35.2/_images/country_map.png> was created. I want to do something similar for my country, but I don't know what chart it is, or what data format to use. I would really welcome a minimal working example behind that. The gallery only points to the static images which is of no help in this regard. Thanks, Gabor
