Here's one I just found: http://fathom.info/projects/countyhealth.html

I've seen a lot of others like these--do you mean to ask about a more specific kind of visualization?
UnfoldingMaps is a library for map display, map interaction and geovisualisation for Processing.
Some examples here: http://unfoldingmaps.org/
I had a small question. I actually would like to build an application which is very similar to( http://tillnagel.com/2011/06/tilemill-for-processing/ ) but as a map and not on “Multi touch Table Top”.
The functionality I need is
Plot different cities of California with different radius, the different radius will represent number of times a person has visited a city.
When a person clicks on a city e.g LA it should show plot a polyline to different cities which are nearby. As shown in the link above.
I was wondering if you could help me on this, if you could give me a right direction to start with will be real great.
