Choropleth Map


- A Choropleth map portray quantitative data as a color showing the density, percent, average value, or quantity of a phenomenon within the boundary of a geographic area. Each color represents a range of data values that were determined by classification techniques that grouped ranges of data values into classes.
- The map above is attempting to show the spread of the 2004 United States electoral votes, and how they might be unbalanced.
