Motion Chart of the 2012 Republican Presidential Nomination

This motion chart depicts the polling from the 2012 Republican presidential nomination. It is a flash and javascript based Google chart. The chart can display information in a variety of ways including a motion chart, bar chart, or line chart (you can switch between them in the upper right corner). Pressing the play button shows the change over time in polling. Clicking on a specific candidates' circle will leave a trail showing their polling over time. You can see another example of a Google motion chart I've created here.
