Maps

Dot Density: These maps place single dots as data points on a regional map. As the dots continue to be added, the locations that contain more points clearly become denser and darker,

Chloropleth: This type of map sets each region to a certain color in order to distinguish certain data locations. In the example below, the darker the county, the more Hispanics that live in that county.

Isarithmic: This map is similar to the chloropleth map except the colored regions are not bounded by predetermined regions but rather based on statistical data alone.

Proportional Symbol: These maps place the same symbol in each region but use the size of that symbol as the indicator of the data.
