3-D Scatter Plot Map

3-D Scatter plot maps, employ the same method of one dimensional scatter plot maps in that they visualize numerical data and coordinate it with a trend in order to add ease to of interpretation to the viewer. However, multi-dimensional scatter plots differ in that they offer multiple degrees/ aspects of the same set of information and coordinate the trends all in one chart. The scatter plot below, for example, shows the percent of white per capita income on the depth of the Z axis, the percent of white degrees on the vertical Y axis, and the percent of white total population on the horizontal X axis. By adding the third dimension of the Z axis, and representing its depth in the variation in dot size, cartographers are able to add another element of measurement to the scatter plot.
