Right click on the map and choose "Edit Data" or click on the map and choose Chart Design > Edit Data in the menu ribbon. As said before, PowerPoint lets us choose between mapping the world or only a continent, focus on a country or using postcodes to draw regions and areas.

Head on over to the Insert tab on the ribbon, and then Charts, on the left of center. Half-way down the list, buried in the bars, lines, and radar charts, you find PowerPoint maps. You get a map template and an Excel sheet.
