Imitation & enhancement of:

Using data from:
http://www.econ.umn.edu/~holmes/data/WalMart/index.html
http://www.econ.umn.edu/~holmes/data/WalMart/store_openings.csv
Here are some of my improvements:
o I made it slightly larger, so I can show more detail.
o I used transparent markers, so you can see locations where Walmarts are "stacking up".
o I use a 'projected' map, so the U.S. doesn't look funky/squished.
o I use larger labels for the year & summary counts.
o I let the labels share the map's white-space.
o I label the states.
Note: This example uses new SAS 9.4 syntax for the gif animation.
