590 Cities is a rather 'crowded' visualisation but worth exploring..It has a large image, which contains information about the eponymous 590 cities.
It's a stack flow chart, by Barcelona-based Bestiario that manages to pack details of 590 cities into a single digital square. The visualization depicts the world's 590 most populous cities, sorted column by column according to their population size between 1950 and 2010, with projections for 2015, 2020, 2025, and 2050. By rolling over the lines you can highlight individual cities' growth trends. Tokyo, for instance, is the fat magenta bar at the top, a position it snagged from New York-Newark back in the 1950's. (Note that in the "normalized mode" cities are plotted relative to one another in each column, so the trend lines reflect relative, not absolute, changes in population — explaining why Tokyo is a flat line despite obviously having expanded since 1955.)
