Eric Fishcer: City heat maps

Fischer, a ‘data artist’, applies Twitter data gleaned from Gnip in the mapping tool MapBox to help visualise where temporary visitors go in cities. San Francisco (top left) and the Golden Gate bridge, for example, attract far more non-locals than Oakland across the bay. The concentration of red to the south is San Jose.
