Proportional Circle Map


A proportional circle map is a type of thematic map that presents the data in the form of circles proportional to the size of the unit being measured. A small circle would indicate a small value, and a large circle indicates a higher value. This map uses different colors to represent different areas of the world. It then illustrates the life expectancy of people at an average income level for that area of the world.
