Microsoft previewed one of its new technologies from the labs, the Pivot.
(on a separate note, while watching the video I realized that till now I didn’t know how to spell pivot correctly)
From the video, it seems that new Pivot does the same thing as it’s desktop older brother in Excel, namely allows to slice a collection of data along available dimensions.
What new Pivot seems to offer on top of that is a more immersive way of exploring data sets, especially those whose items can be visualized somehow. So it’s like a very visual drill-down capability.
