Having said that, I'm not sure if the colors were important enough to merit being included. Do I really care that some occupation gives people a better chance of being in the 1%? Probably not. I'd rather see how many total dollars we are talking about. For instance, do the 1% working securities law make a bunch more than the 1% who are construction managers? By how much?
I'll attempt a tl;dr, although you really should read the article. The 1% consists mostly of: managers, physicians, and lawyers, maybe with elementary and middle-school administrators thrown in as well.
I would caution to be careful of drawing too many conclusions, however. Every time we have these discussions it's the little details that always get you. It's very easy to feel like you are learning more than you actually are. Always be suspicious of aggregated data, especially when you are looking for insight. I blogged about this last month.

Guys like lawyers and school principals fit into nice, little boxes. Entrepreneurs don't. I run into this every time I fill out a government form. For instance I know a guy locally who runs a couple of convenience stores, sells fuel on the side (by "on the side" I mean hundreds of thousands of gallons or more a month through home heating oil trucks, propane, etc.) , has a go-cart track, and is getting into e-commerce. What do you call him? A fuel speculator? Grocery manager? Entertainer? We talk about this all the time on HN, even though we don't know it. Take your average startup, say Stripe, are they a technology company? We would probably say so, but they also look a lot like a financial services company. How about the guy who's a lawyer and helps startups in a participatory manner for equity. Is he a VC? A lawyer manager? A partner? Yes, I know the IRS has legal definitions, but when looking at data like this the legal definitions don't really fit the discussion -- it just leaves us more questions than we started with.
The category of many of these business alone is problematic, much less trying to figure out job titles. Real innovation happens between the cracks. It doesn't fit into nice little boxes. The economy works because people are free to pick and choose little bits of all kinds of things to refashion them into something new that never existed before, so the parts that aren't being tracked here are the most important. Once you start looking at aggregates, averages, and deviations, you can make numbers say about anything you want.
