With this data map, circles are displayed over a designated geographical region with the area of the circle proportional to its value in the dataset.
Bubble Maps are good for comparing proportions over geographic regions without the issues caused by regional area size, as seen on Choropleth Maps. However, a major flaw with Bubble Maps is that overly large bubbles can overlap other bubbles and regions on the map, so this needs to be accounted for.
