BUBBLE MAP

BUBBLE MAP

Description:

• A bubble map uses circles of different size to represent a numeric value on a territory.
  
• It displays one bubble per geographic coordinate, or one bubble per region (in this case the bubble is usually displayed in the baricentre of the region).
  
• 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.
• The x-axis is nothing but each end of the spider and each step of the spider considered as Y-axis.
• Zero point of the radar chart starts from the centre of the wheel. Towards the edge of the spike, a point reaches, the higher the value.
• It is a X vs (Y1,[Y2]....) graph.
  • X-axis represents one set of data.
  • Y-axis can represent single or multiple data sets.
