Undergraduate Grades Chronologically

Here's round two of me playing with representing my undergraduate grades. This time I've used Processing which is a neat programming environment for doing these kind of visual sketches.

This has some of the same ideas as before, the radius of the circles represent the credits for a particular department or course. This one, however, is interactive. You can mouse over the department circles to see only the courses from that department on the graph below. You can also mouse over the courses on the graph to see what they are.
