Bike Sharing Worldwide - Visualized

Ramnath Vaidyanathan does some heroic lifting with R based on the CityBikes API to provide a real-time view of bike-share availability worldwide.  As he puts it

A couple of months ago I had posted an interesting application of using rCharts and Shiny to visualize the CitiBike system in NYC. I had always wanted to write a tutorial about its inner workings, so that it would be useful to others looking to build similar visualizations, and I finally got around to doing it. Along the way, I managed to extend the visualization to around 100 bike sharing systems across the world. The final application can be viewed here.

The below are just screen grabs from the app for New York, and London.  Go to the site to actually mess around...
