Filled map chart
A filled map chart is a map chart that carves out the coverage areas of each geographical location supplied and uses a dark-to-light color fill to present the values for each location. It is a good chart to use for location-based data as it adds the geographical positioning insight that is lost when other chart types are used.
Figure 8.43 is an example of a filled map chart showing the sales for a retail company across different Canadian provinces:

That wraps it up for the filled map chart. We will move on to the last chart type.
