Voronoi Heat Mapping


Biking from Place to Place is a neat visualization of Chicago's bike share network. The map uses a very clever Voronoi heat map technique which allows you to find out the number of bike trips from any bike station and view the most popular destinations from each station.

Select a bike station on the map and you can view a heat map showing the most popular destinations from that station. The map provides some interesting insights into the travel patterns of Divvy bike users. For example, if you select a bike station along Lake Michigan you quickly notice that most Divvy users borrow bikes here to cycle to other bike stations along the lake shore.

The heat map overlay uses a very clever Voronoi map technique which allows you to find the nearest bike station to any location. If you point to any location on the map the nearest bike station is automatically selected for you and the Voronoi heat map overlay also shows you the areas around the destination stations. This provides an insight into the likely final destinations of the bikes' users.
