This graphic is from The New York Times graphics department. It matches the FlowingData colors. That is all. Oh, and it's excellent, but that's a given, right? Note the use of each bar's two dimensions.
It’s nice to have some pull at the NYT, to get them to use your color scheme so the graphic assimilates well into your blog… It took me a bit to get use to the height metric, but I like it. It’s genius! (to quote one of my favorite lines)
What really impresses me, outside of the amazing visualization, is the added analysis in text on the right. They have done most of the “dirty” work for their readers and pointed out the outliers.
It’s interesting that Obama dominates for male voters.
