BUBBLE MAP

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.
