A geochart is a map of a country, a continent, or a region with areas identified in one of three ways:

  • The region mode colors whole regions, such as countries, provinces, or states.
  • The markers mode uses circles to designate regions that are scaled according to a value that you specify.
  • The text mode labels the regions with identifiers (e.g., "Russia" or "Asia").
(see the doc of Google)
