Boston d3.js User Group Message Board › Hubway Data Visualization Challenge
We are are running a Hubway Data Visualization Challenge in October, deadline is Halloween midnight. If you're interested, you can play around with all Hubway bike trips ever made in the Boston area (over half million trips until the end of September).
Find out more at http://hubwaydatachallenge.org/
The data is available for download as CSV and Shapefiles (geographic location of each station), as well as a simple Data API.
Please let me if you have any questions or have suggestion how to structure the data differently to make it easier to work with d3.js.
There will also be a Hack Day at the Bocoup Loft on Saturday October 27th 2012 (http://hubwaydatachallenge.eventbrite.com/) , which I personally will use to get me feet wet in d3.geo.
