Bitdeli visualization example: Trains arriving to BART stations in next 15 minutes

This example shows how to use real-time data from the Bitdeli API to create visualizations with RaphaelJS.

The visualization shows a BART station on each column. The further the estimated time arrival is for a train, the further it is drawn from its destination station down bottom. The data is updated once a minute. Refresh the page to see the updated status.

The data originates from the BART API through this Bitdeli script.

You can view the live visualization here with bl.ocks.org.
