Chart to show reputation points grouped by event type

I would like to request a pie chart to see how a user got his or her reputation. This could be placed on the profile page. Sections could contains percentages like:

14 Questions - 200 points - 28.41%
20 Answers   - 400 points - 56.82%
 2 Edits     -   4 points -  0.57%
 1 Bonus     - 100 points - 14.20%
