Intermission: Global Statistics, Represented by the Olympic Rings
From designer Gustavo Sousa, an elegant if somewhat confusing little infographic that represents various global stats with the Olympic rings. There's no key, so you have to deduce it yourself. I'm going with green for Asia, black for Europe, blue for Oceania, yellow for Africa, and red for the Americas. There are static versions of these graphics on a corresponding Tumblr.
