is there a way to combine one or more states or countries and treat them as one “piece” in the map?
For instance, I want to group the states NY and CT - group A, color yellow and CA and NV - Group B, color blue. Now i don’t to care about the individual state but about the group. Say I have average temperature for each state, I want only to display each group’s average temperature i.e. Group A average of temperature of NY and CT and Group B average temperature of CA, NV.
Is there a way to group different states or even countries and treat them as one?
