Pi Pie Chart

For today’s special Pi Day version of Bad Chart Thursday, I present to you the distribution of digits in the first 1,000 decimal places of pi, presented as a pie chart:

Remarkably, when I Googled for this, I was only able to find the frequency of digits in pi represented in bar charts, which is obviously a ridiculous thing to do, considering the pun opportunities. So, fixed.

As an accompaniment, please enjoy this related clip from How I Met Your Mother:

But… But this is a GOOD chart! Where is the bad chart? Oh I guess maybe it’s the bar graph.

That show has so very very many excellent episodes, and making charts by hand is one of my guilty pleasures, so of COURSE that’s one of the best episodes.

5. Jackal says:

I did a similar project using the first 200 million digits of pi. The digits came out uniformly distributed at 10.00% each, but I didn’t have a way of verifying that the data I was analyzing were the actual digits of pi.

1. penguinsdemise says:

That sounds right. The numbers of pi are thought to be completely random (though this has not been proven), so 10% of each makes sense.

6. One’s number one! One’s number one!
