Please note that the figures shown on this graph do not represent a count of unique maps. This is because a map covering several countries is counted in each country. If these countries are on the same continent, the map is counted multiple times.

Example: A map covering France and Switzerland is counted in both countries and therefore counts twice towards Europe. This is why the total shown at the centre of the graph is higher than the actual number of unique maps in the catalog.
