For Pi Day, a pie chart celebration

Some prefer apple. Some prefer cherry. When it comes to pie, I like a good chart.

I know today is Pi Day, celebrating the ratio of a circle’s circumference to its diameter — it’s 3.14, and if it’s not quite so exciting as it will be in 2015, it’s still as good an occasion as any for some graphics.


Still want more pie? Maura Judkis has you covered.

And Pi-related events in the district today.
