Saturday — March 14, 2015, or 3/14/15 — marks an extremely nerdy holiday. It is the official celebration of π, the magical, mathematical and infinite constant that is the ratio of a circle’s circumference to its diameter.
For any circle you can imagine, if you divide the distance around the circle by the distance across it, you will get pi, or 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823066470938446095505822317253594081284811174502841027019385…
We could keep going, but you get the picture.
Some people will celebrate the holiday by making and eating pies (Washington restaurants are offering specials on everything from pizza to banana cream). Others will run a Pi-K race of 3.14 kilometers. And some data tinkerers are making art that visualize pi’s infinite and random digits.
One of the best known of these data tinkerers is Martin Krzywinski, a scientist who specializes in bioinformatics, or using computer science and statistics to understand biological data. Krzywinski started publishing his pi art in 2013, beginning with this visualization:
