Africa sized by Wikipedia Articles - a #Visualization

From the Oxford Internet Institute, we have this map of Africa, where the countries are resized based on the number of Wikipedia articles about them.
Looks surprisingly correct, except for Central Africa that is somewhat slender - probably due to the extremely limited internet access in a bunch of those countries (Check out the Sudans and the Congos in particular...)

Mind you, this has nothing to do with the actual quality of the articles on Wikipedia...
