Woah, this is exactly what I was looking for. I had vaccination data that I wanted to visualise but seemingly nothing in the market makes it easy to put it out there fast.

Google chart library is great (if you have heard of it) but they come with restrictions on their geocharts. They require Google Maps Platform API key in the client which made me reconsider using it. I only needed a simple choropleth chart for which static geojson feature file would work, no need for fetching from Google maps for every user.

Great work. I will check it out.
