Chloropleth map

- Rt
- Total cases, Active cases, Deaths per 1000
- Posrate
- Test per million
- CFR
- more..?

Thumb rule: data visualised on a chloropleth map should always be a rate /ratio or adjusted for population.
Demo using datawrapper for RT (old data): https://datawrapper.dwcdn.net/tp6r3/4/

Live chloropleths using datawrapper: https://academy.datawrapper.de/article/236-how-to-create-a-live-updating-symbol-map-or-choropleth-map

Other options:
https://leafletjs.com/examples/choropleth/
https://plotly.com/python/choropleth-maps/

Start by inspecting the frontend repository structure and reviewing the linked Datawrapper RT demo, live choropleth guidance, and Leaflet and Plotly examples. Clarify which metrics and mapping approach are in scope; done should mean an agreed live choropleth implementation covering the selected rate or ratio measures.
