Using data downloaded from:

Rather than just using Proc Gmap's 'levels=' option, 
I assign my own buckets for the legend binning,
and then use a user-defined format to make the numeric
buckets print as the desired ranges of values.

I use the new/simple animation syntax, and plot the maps
'by year'. I use a 'note' statement to print the #byval(year)
in very large font size in the bottom/left of the map.

Note that there is html hover-text for the state names
