Cartography

Cloropleth maps use color or different intensities of shading to indicate the statistical difference on a map.

The map below shows the population density for each state

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.

The map below shows the range of precipitation across the country.

Another type of map is a proportional symbol map which shows intensity of the number that the map is showing by having a larger or smaller symbol. 

The map below shows the population of hispanics per state. As we can see, the population is larger in Texas.

Another type of map that we studied is the dot density map, which incorporates the location. In these maps, location is crucial because it locates where the specific statistic is located.

This map below is also a representation of the hispanic population, but this map is more accurate than the one above because it shows the location of the populations.
