What Is a Thematic Map?

Thematic maps portray attribute data about locations and features.

Create Choropleth Map of Population Density

This example shows how to create a choropleth map of population density for the six New England states in the year 2000.

Colormaps for Political Maps

Political maps typically use muted, contrasting colors that make it easy to distinguish one country from its neighbors.

Contour Colormaps

This example shows how you can create colormaps that make surfaces look like contour maps for other types of data besides terrain.
