I was just checking out the stuff at http://analyticsvisualizations.appspot.com/juicekit/AnalyticsVisualization.html
Basically you login using your Google Analytics account (or actually uses the Google Analytics API) and bingo you can see the referral flow or tree for keywords to your website.
It is very very cool stuff by http://www.juiceanalytics.com/
One particular dashboard I have been thinking of is- uses Google Analytics data to not only show trends in traffic but also forecast traffic for posts using certain keywords or categories (assuming simple time series + X forecasts)
