There is something strangely mesmerizing about maps with a lot of dots. The project Mapping Wikipedia [tracemedia.co.uk] consists of an interactive world map that reveals all geo-coded Wikipedia articles that are published in at least 1 of 7 different languages: English, French, Arabic, Hebrew, Farsi, Swahili. The impressive visualization was developed by TraceMedia using an analysis of Wikipedia by the Oxford Internet Institute.
As a result, the map shows the global distribution of articles written in each language. One can also explore some quantitative parameters that can be associated with a typical Wikipedia article, such as word count, number of authors, number of images, and so on.
Accordingly, people in the very north of France seem to be particularly proficient in writing long articles, together with people traveling along an east-west highway in northern Spain, I think.
