Here's a static example for what I'm thinking about doing. It has the top two colleges on both lists. Note that I haven't figured out how I'm going to indicate which college is on which list, but I'm not sure I'm going to - maybe I should leave some mystery up to user/reader?

Is it clear what things mean here? Especially the circles? The gender signs and colors should help, but also I wanted the size of the circles to represent campus population roughly. They're not exactly in proportion to one another, since they would have to be either some really really really tiny ones or some really really huge ones, but I think it gets the idea across.

Let me know what you think. Thanks.

Sketch

There was a bit of confusion with the location on the last post, so I'm just going to get rid of that part of information. I sketched a few from abstract -> literal based on what would be relevant to the effects of fast food products. Main ones would be how much of the product is consumed, which leads to health issues and obesity. Gender and age is also shown.
