Explanation

Each digit of pi is a quarter-circle with the radius of its respective digit, and the end of each segment is connected to the start of the next.

The first digit of pi is 3, therefore the first circle has a radius of 3; the second digit is 1, therefore the second circle has a radius of 1; etcetera...
