Yesterday was National Pi Day. That’s Pi as in 3.14…not as in pie pie. Unless you celebrated Pi Day with pie. In which case, way to go, you. Me, I’m more traditional. I celebrated Pi Day with talk of pie charts. But at the Wonkblog over at the Washington Post, Sarah Kliff posted about several really impressive pie charts.
My favourite was the actual advertising done by the Economist back in Philly a few years ago. Their advert was printed atop a pizza pie box. It’s the double-whammy of Pi Day: pie charts atop a pizza pie.
Thanks to my co-worker Eileen for passing on the tip.
