Univariate choropleth maps

Unlike a Bivariate choropleth map, which displays two unrelated sets of data, a univariate map only displays one variant. In the map above the colors represent the water usage in millions of gallons per day.

Nominal area choropleth map

In this map the colors represent different provinces in Iraq. With each province comes a different political system and varied beliefs. The names of the provinces are clearly marked.

Isopleths

An isopleth map generalizes and simplifies data with a continuous distribution. It shows the data as a third dimension on a map, thus isopleth maps are more common for mapping surface elevations, amounts of precipitation, atmospheric pressure, and numerous other measurements that can be viewed statistically as a third dimension. This map shows Sulfate ion concentration in the U.S.
