Worldmapper is a group that produces maps of the world – with a difference.
Worldmapper shows what are called equal area cartograms, where territories are redrawn according to a particular variable.
The sea is always the same proportion of the map. The colour and shade for each territory is the same on every map. As far as possible, the territory shape and relative positions are also preserved. The process of creating an equal area cartogram has occupied researchers for decades.
Area corresponds to area.
Area corresponds to cereals exports.
Area corresponds to number affected by disasters.
And there are lots more where those came from!
