Working with Geo Maps

About Geo Maps

A geo map displays your data as a bubble plot that is overlaid on a geographic map. Each bubble is located either at the center of geographic region or at the coordinates of a location.
In order to display a geo map, you must define one or more of your categories as a geography data item. For more information, see Define a Geography Data Item.
