And then there are the maps, network diagrams that are intentionally distorted to simplify information at the expense of geography. "Riding an underground train robs us from using visual references of the city," emails Till Nagel, a research associate at the Interaction Design Lab in Potsdam, Germany. So how do subways change the way we perceive geography above ground? To play with this question, Nagel and Benedikt Groß created a clever animation of the Shanghai metro system, one of the busiest in the world with more than 8 million rides a day. This is an actual map of the region, with the subway network accurately overlaid on top of it:"
