Range graded proportional circle maps consists of data mapped with a circle instead of a dot. These maps are a type of point pattern analysis maps. The sizes of the circles relates to a measured variable, not the area over which it is measured. In this type of map, range graded, there is only a set number of circle sizes used. These sizes usually correlates to a specific amount of measured data. The map above uses range grading to show the number of people killed in road accidents in parts of Europe.
