A SAS/Graph entry in the IEEE VAST challenge

The IEEE Conference on Visual Analytics Science and Technology (IEEE VAST) recently had a data analysis contest.

The data was a bit daunting (being somewhat "large", with over a million observations, and with various pieces of the data in various different formats), but I was able to handle it with SAS, and prepare an entry in each of the 3 "mini-challenges", and also the "grand challenge".

If you'd like to see them, here are my results. I spent the most time on mini-challenge #1, since it involved mapping (my favorite):

How did you do the Grand challenge charts?

is that a scatter with a map as background?

It's a real "map", rather than a scatter plot. I created a rectangular gmap map area with the same lat/long extents as the photo/image had, and then I annotated the photo/image onto the map. Once I had a real map with the same lat/long extents, I could annotate the microblog lat/long point-data (red markers) onto the map.

Here is another similar example (but in this case, I'm actually combining the image with a map you'll recognize)...
