U.S State Visualization example - Long commute - Another D3 example

Here is another example of using D3 to generate stats driven visualization.  I wanted to read the data from Google spreadsheets but then the lazy me thought that it will be easier just to add the traffic ratio attribute within the “us-state-centroids.json” file. Here is how it looks now :

The large circles indicates large commutes. As you see most of the data is not even complete and since this just a work in progress, I wil make another revision to it hopefully shortly. The full html file to the U.S visualization can be found here.
