I am using python to visualize how a polygon (not yet with multipolygon) can be visualized within this map.
python -m venv env-namesource env-name/bin/activateApip install numpyDo this after u finish coding session or sth, or wanna fk of frm env
deactivateMake sure your env has all the lib inside requirements.txt. Usually just run this when you activate your environment already.
pip installInside ./script.py, change this line to your prefered polygon coordinates.
...
border = "SRID=4326;POLYGON((101.3260618 0.5985796,101.3277795 0.5965827,...))"
...Run this to execute
python script.pyYou will see changes inside ./polygon_map.html, then you can open it in your browser to see the map with the highlighted area.
