Geo clustering - Brazil map

I work with public education in a non-profit organization in Brazil. Right now I’m helping the team monitor the schools re-opening after COVID-19 breakthrough.

I’m considering using Coda as a tool, by applying a geo clustering and data heat-map.

The idea is simply: build a better user experience (since we started using spreadsheets).

I know about this example from template map application but my preliminary test wasn’t successful to add Brazil states (instead of US states).

Someone knows (or have any tips) on how can I address this solution?
