Ask HN: Graphical Analysis for Pivotal Tracker?

I am a freelance contractor who is putting together a proposal for Pivotal Labs to add graphical analysis to Pivotal Tracker. My question for HN is: what new features would you like to see in Pivotal Tracker?

Pivotal Tracker already includes a couple of visual analyses, including the velocity chart, burndown graph, and point breakdown report. Are there any other metrics, or different approaches to those metrics, that you think would be helpful in visual form? On a larger scale, are there different groupings of data that you think would be useful, such as cross-team comparisons, or progress reports for each individual?

Thank you for your responses!
