Continental and regional maps require only two data columns or rows from your DataSet. One column or row contains the names or two-letter ISO codes of the countries in the continent or region, and the other contains the values for each country. These values are represented in your map by varying shades of color, each of which corresponds to a specific range. Ranges are determined automatically based on the distribution of values in your DataSet and are represented by a legend, which is automatically included beside the map.For information about value, category, and series data, see [Understanding Chart Data](/s/article/360043428693 "Understanding Chart Data"). **Note:** When multiple instances of a single region occur in a DataSet, the values for that region are summed to show a single value for the region in the map. For example, if your DataSet contained three rows for "Georgia," the values for the rows would be summed, and the Georgia region in the map would show the total value. You *cannot* turn off this automatic aggregation in maps. For information about world maps, see [U.S. County Map](/s/article/360042925074 "World Map"). For information about troubleshooting when an area in your map does not show data but there is data, see [Troubleshooting Domo](http://domo-support.domo.com/s/article/360043427473?language=en_US). **Video - Map Charts**
