An intensity map, also known as a choropleth or thematic map, colors the outline of countries or provinces darker or lighter according to the number in a specific column.
In order to use this visualization, your table must have a location column. You can set your location column manually.
To make an intensity map in Fusion Tables:
- Select Visualize > Intensity Map.
- In the Value pull-down, specify the column with numbers to use to color the map
- To focus in on a region (eg: Africa) or a specific country, enter the name into the Area text box.
