Tracking Taxi Flow Across the City

This is a really spectacular heatmap of Manhattan showing where taxis are picking up fares across the borough. An extra dimension of this visualization is the ability to watch the data change over the course of the week by playing the animation. Now that taxis in NYC have mandated GPS systems installed, very rich information can be extracted and mapped like this. Taxi pickups peak at major tourist shopping districts and transportation hubs such as Penn Station and Grand Central Terminal.
