Choropleth map

A choropleth map (from Greek χώρο ("area/region") + πλήθος ("multitude")) is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income.

Description

The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region.
