National Pi Day

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.

The image below comes from a different site about the Economist ad campaign, found here, but the link goes to the celebration of pi with pie.

Thanks to my co-worker Eileen for passing on the tip.

I am a graphic designer who focuses on information design. My day job? I am the data visualisation manager for the Federal Reserve Bank of Philadelphia. (This blog is my something I do on my own time and does not represent the views of the Fed, blah blah blah legal stuff.) And with my main interest in information design—be it in the shape of clear charts, maps, diagrams, or wayfinding systems—I am fortunate that my day job focuses on data visualisation. Outside of work, I try to stay busy with personal design work. Away from the world of design, I enjoy cooking and reading and am interested in various subjects from history and geography to politics to science to the arts. And I allow all of them to influence my work.
