New card type that matches the Data Center.
The data center visualizations are so cool that it would be awesome to power up a card of my own. The controls wouldn't be inherantly different than any other card. Data center drill downs basically result in an x/y value type chart, adding a series could change the saturation of color if one were so inclided. Clicking on any one of the displayed cubes would take you to the data that backs that cube, just like the rest of the KPI cards.
