Andrew Zolnai shows how quickly you can start working with Google Fusion Tables and Google Maps. There are limitations to Google Fusion Tables that will probably confine it’s use in the near future (data has to be public), but that will all be resolved when it becomes part of the Google Docs suite soon enough. I really can’t imagine visualizing data outside of Google Fusion Tables anymore with web mapping. The pieces are all there.
