Classed Choropleth Map

Classed Choropleth Map
A classed choropleth map provides visualization of how a measurement varies across an area, or the level of variability across a region. Shading is used to show this proportion of statistical measurements. Having too many classes for a map can make it more difficult to read and the colors can distort the actual information; 4 or 5 classes is usually enough. This choropleth map shows the amount of spending by overseas residents in 2003.
