CHOROPLETH MAP
Description:
- A choropleth map is a type of thematic map in which a set of pre-defined areas is colored or patterned in proportion to a statistical variable that represents an aggregate summary of a geographic characteristic within each area, such as population density or per-capita income.
- Choropleth maps provide an easy way to visualize how a variable varies across a geographic area or show the level of variability within a 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.
- It is a X vs Y graph.
- X-axis represents one set of data.
- Y-axis can represent single set of data.
