OD Viewer

OD Viewer is visualization of Auckland, New Zealand's 2014 origin-destination rail ridership. Rail station arrivals and departures are represented by color- and size-coded circles centered on the rail stations.

Absolute or percentage sizing can be chosen from the menu. Clicking on a station then re-sizes all other stations using the selected sizing method. Hovering over a station displays its arrival/departure value.

The selected station can be made the origin station or the destination station. If it is made the origin, then it will be sized according to the number of departures from that station, and every other station will be sized by the number of arrivals it receives from the origin station.
