Michael Frumin tried to get some NYC subway data from the New York City Transit Authority through Freedom Of Information Legislation for a project he wanted to do, but they denied his requests. "Given a database of anonymized Metrocard 'swipes' over some small period of time, Frumin imagined that a multitude of explorations could be embarked upon. Below is a concept sketch for one specific project idea -- a visualization, for each station in the system, of the range of locations in the city that people travel to from that area." Nice Minard-esque prototype map.
