What is the difference between a dot map and a choropleth map?

Answer 1

Dot maps use dots to represent a stated amount of some phenomenon within a political unit. Using a scale equating one dot with 1,000 people, 12 dots in one area would represent 12,000 people living in that area.

On a choropleth map each political unit is fulled in with a distinguishing color or pattern but instead use lines to join points of equal value across the mapped area.

So in short, one map uses dots, and the other uses lines.

Answer 2

A dot map represents data using individual dots placed at specific locations on a map, with each dot typically representing a certain quantity. A choropleth map uses colors or shading to represent data values for predefined areas, such as countries or states, where the color intensity or shade varies based on the data being depicted.
