Geo Maps

A geo bubble map is a bubble plot that is overlaid on a geographic map. Each bubble is located at a geographic location or at the center of a geographical region. The bubbles are automatically colored based on the location. You provide a measure data item that determines the size of the bubble. A geo bubble map requires a data item that contains geographical information and is assigned to a geography role.

A geo coordinate map is a simple scatter plot that is overlaid on a geographic map. A geo coordinate map is used in place of a geo bubble map when the cardinality is too high and the geo bubble map cannot display the number of points. Each point in a geo coordinate map is located at the center of a geographic region or at the coordinates of a location. A geo coordinate map requires a data item that contains geographical information and is assigned to a geography role.

A geo region map (also known as a choropleth map) is a two-dimensional map that uses color combinations to represent different categories or levels of magnitude. You can fill geographical boundaries (for example, a country or a state) on a map with color, based on measure values that are aggregated to the level defined by a geographical boundary.
