Thematic maps portray attributes of locations and features. For example, a thematic map could show the population density by region, or election results by state.
This example shows how to create a choropleth map, in which the color of each state represents the population density of the state.
Political maps typically use contrasting colors that make it easy to distinguish one country, state, or province from its neighbors.
This example shows how to create colormaps that make surfaces look like contour maps. You can specify the contour interval, add a colorbar, and restrict the displayed value range.
