Pi Day is March 14th (03-14, in US dates), so I have put together a pie chart of Pi Day activities. I tallied reader responses about how people celebrate the holiday and put it into a pie for you. If you'd like to add ideas for Pi Day activities, you can post a reply or add your response.
You're welcome to download and use the pie chart. It is available as a PNG image or PDF file.
