I wish there were three additional views to this data: 1) Average salary, adjust the circles such that they change shape based based on this value. 2) Total $ spent on employing people in this occupation 3) Average cost to train someone in this occupation It could get real interesting if you could intersect data like average salary with the number of people in a field, and the cost to benefit ratio of training v's income once on the job. I think we all know what direction it would point in, but it'd be nice to see it regardless...and hey, maybe i'm wrong? [although we know that's unlikely here]
