Hi Itai,Do you have the GeoJSON that contains the boundary information for these regions? If so, you can load both the csv and the GeoJSON into the same CODAP document and then drag your “REGION” column onto the matching region name column in the CODAP table that has the boundary information. See these help docs for how to join tables:
