Google's Fusion Tables look impressive, for those who want to try geo-visualizations of their data. You don't need much programming experience to be able to use it.
For those who want to try it out, here's a nice intro that Kathyrn Hurley presented at the recent SVCC (Silicon Valley Code Camp). When combined with ShpEscape (note spelling) it becomes very powerful.
The Guardian (UK), Texas Tribune, and WNYC seem to be organizations that are taking advantage of it.
I'll post a couple of their examples soon. If you have a Google account, it's easy to test out Fusion Tables.
