Mapping with Bubbles

This would be an interesting method to just map a city based on cell phone usage. It will also allow to graph the different behaviors of users and places visited most. I think this concept could open the doors to various possibilities such as getting details on demographics. The downside I see is that it is sometimes creepy have locations of where you visit from cellphones.

Browse local data from the Census Bureau’s american Community Survey, based on samples from 2005 to 2009. Because these figures are based on samples, they are subject to a margin  of error, particularly in places with low population, and are best regarded as estimates.
