After you’ve inserted a map in your project, you can add or edit its data set at any time. Simply double-click on a map to edit the data table.
When importing data, be sure to keep the following formatting and layout of the default dataset for the map to display correctly.
Column 1: country/region names
Column 2: numerical data
Column 3: grouping entries (this column will be used if you have selected the Grouped map style in Map properties drop-down, in map settings)
Column 4: coordinates (automatically populated when Column 1 is filled out)
Column 5: labels (whatever you insert in this column will be displayed in the map tags when you hover over data points)
