D3 animated pie chart

Lots of people in the data viz community hate pie charts. Gussied up pie charts – exploded, 3D charts that needlessly complicate presentations – are considered especially heinous. Still, I'll do you one better.

This is an animated, D3 pie chart that displays several categories of information about a group of students. Rather than make five separate, static charts, which would present the same information in considerably less time, this one packs it into one and does a song and dance, too.

Unfortunately, the chart is not optimized for mobile, so I hope you're on a desktop browser right now. Also, grouping colors to indicate subcategories would be an improvement. For example, majors could be grouped by hue into humanities, sciences, etc.
