Well according to this map, much of those south eastern states have low income and high inequality. What does that really mean in terms of people though? Does that mean there are lots of white and black people that are similarly poor and a relatively small proportion of very wealth people living in the state (with not as many people in between)?

I wouldn't be surprised if this has to do with how poverty is more widespread across both black and white populations in those states. There is some correlation between poverty and crime. I'm not saying that wealthy people don't commit crimes, but often by the nature of their crimes, selective crime enforcement, and well-paid lawyers, they are less likely to be convicted or given long prison sentences.

It would be nice if it also compared IPOs to the current market capitalization.

This visualization makes going through the data a lot more pleasant than just viewing the Wikipedia page. However, I wonder if you tried out including graphics to denote when some movies skip a decade before showing up on the list again (e.g. a dotted line). Or would that add too much clutter to the visualization.
