Back in December 2010 Microsoft research decided to re-release Pivot which provides a graphical method of exploring large amounts of data.

Pivot is an experimental application for exploring large data sets with smooth visual interactions. The application originally was released by Microsoft Live Labs in October 2009, and it is being re-released by Microsoft Research to enable the research community to continue to use it for experiments. If you have Internet Explorer 9 installed, disable GPU rendering in Internet Explorer to enable Pivot to work correctly. The Pivot collection home page points to content no longer available, but Pivot still can be used for viewing user-created local or web collections. This standalone version of Pivot is unsupported and might stop functioning properly in the future.

Here is a demo video from NeoWin that shows Pivot in action:

Pivot requires Windows Vista and above plus at least 256MB of RAM.
