I got one of my harder requests today. A patron needed a radius population map of City in 5, 10, 20, 30 and 40 mile increments. I have a database to use, but I wasn't sure how to get that kind of map. I've messed with the database before, but not in that capacity.
After playing with it for about fifteen minutes, I had a radial map, and a separate page of the demographics in those increments. I got the info to the patron, then told her that if it wasn't quite what she was looking for, to let me know and I'd see what else I could do.
Luckily for me, it was what she needed.
