Finally, another Silverlight RIA to add to the DesignGalleRIA.

MS built this cool PivotViewer. It is a visual way to explore lots of data. Go check out the demos and play with the live filtering. There are 4 demos in total, same interaction design, different data sets.

If I was going to incorporate this in a product, I would offer a visual pivot viewer plus a standard pivot table for exploring data. Dundas has a decent design for the standard pivot table/ OLAP cube.
