I probably should have thought a bit more before I replied since I
have not done this before. I was just trying to think of a way that I
might do it. I do not know how to directly download that file from
Google.

Making maps like this in R is fairly easy since there are some nice
examples such as,
http://cran.r-project.org/web/packages/spdep/vignettes/sids.pdf

I am not aware of metro area files in R, though there are state and
county files in the maps package. But, I was thinking that you could
locate a metro regions shape file of the US and map the colors based
on the attributes in provided in the csv file on the Google page.
For example, Top metros for cold play, Harrisonburg = 100, etc. etc.

I am not sure how many you need to do so this may not be very efficient,
Sorry I couldn't help more,
Michael
