I want to reproduce the dynamic US map showing the obesity percentage across the years 1984-2009 as shown in the CDC website http://www.cdc.gov/obesity/data/trends.html
I am looking for tools and code to get started on this.
EDIT 1 (Apr 22 2011)
I was able to gather the data (1994-2009) and I have uploaded it to Google docs in csv format.
Using R and googleVis I was able to generate a map for a single year (say 1994) using gvisGeoMap. But I want to create a map which will motion through years 1994 to 2009. I am not sure how to add the motion ability to gvisGeoMap. Do I need to look at some other tool?
