Support iso2c codes for choropleth map

After some testing I noticed the Choropleth Map expects ISO codes for countries and US states. Oddly enough, the US states map works with iso2c codes, while the countries map expects iso3c codes.

Would it be possible to have the Choropleth countries map work with iso2c codes automatically as well? And/or to document the expected input format? I didn’t find anything choropleth related on

Hi Peter,

This could be a bug, looking into it right now.

Peter, Found the root cause, and just fixed now. It will be in the next version, which is due in a few days.

Will the documentation also be updated to include a choropleth example and what input is expected? Currently you have to guess that it needs to be ISO codes.
