BUBBLE MAP
Description:
- A bubble map uses circles of different size to represent a numeric value on a territory.
- A list of geographic coordinates (longitude and latitude) and a numeric variable controlling the size of the bubble. In the previous example, the number of tweet at each unique pair of coordinate was used..
- Bubble Maps are good for comparing proportions over geographic regions without the issues caused by regional area size, as seen on Choropleth Maps.
- 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.
- Bubble Map has X & Y axis.
- It is a X vs Y graph.
- X-axis represents one set of data.
- Y-axis can represent single set of data.
