Gerry Crispin just reminded me that I hadn’t checked in to see if Google had ever done anything with the Trendalyzer software they purchased from Hans Rosling a few years ago (video from TED here). Apparently, they did. If you like the way the trend software looks you can load it up as your very own. I have not played with it yet, but you can grab the gadget here (called Motion Charts) and the APIs here.
If you haven’t seen this in action, watch the TED video, it’s very cool.
