I am looking to put county and demographic information on an interactive web map. Something simple might do at first, but eventually, I'd like to put large amounts of demographic information on going down to the Census block group or Census tract level. (Lots of data.)
I'd like for people to be able to mouse over a county, for example, and see the actual stats in a pop up. Free or inexpensive software is what I'm after.
Stat Planet seems ok but looks very basic http://www.statsilk.com/software/statplanet. Maps Alive looks pretty good http://www.mapsalive.com/Samples/. What I don't want are those tacky tacks like on the Google maps (no offense to anyone).
Any information would be appreciated.
