One of the interesting sessions that I attended at DrupalCon DC was one entitled: Business Analytics in Drupal with Views. In it, the presenters showcased two of their modules. One was a charts display plugin for views, and one was a 'group by' views field.
Views charts
This was a simple module to take the output of a views query and pump it into a flash charting framework. Being able to display the output of your views with charts is really nothing new, and the presenters admitted to duplicating existing modules. Hopefully a module will emerge from the mess...
