DEFINITION

What is a dot-density map?

A dot-density map is a type of thematic map that uses dots or other symbols on the map to show the values of one or more numeric data fields. Each dot on a dot-density map represents some amount of data.

In a dot-density map, areas with many dots indicate high concentrations of values for the chosen field and fewer dots indicate lower concentrations.
