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?

I would look at the google visualization API: http://code.google.com/apis/visualization/documentation/gallery/geomap.html

If you are familiar and comfortable with R, there is an R interface that may simplify things: http://cran.r-project.org/web/packages/googleVis/index.html

Thanks Chase for pointing to the GoogleVis R package –  Anand Apr 18 '11 at 22:19

I would recommend the above Google/R route if that is what you are comfortable with.

Alternatively Polymaps has some great looking data visualisations http://polymaps.org/

Finally here is a tutorial for creating animated maps in Google Earth
