This diagram represents the first 1500 digits of pi. The digits are represented as a path traced by links between successive digits.
Each digit is assigned a segment around the circle. The "14" in "3.14..." is drawn as a link between segment 1 and segment 4 .
The position of the link on a digit's segment is associated with the position of pi. For example, the "14" link associated with the 2nd digit (1) and the 3rd digit (4) is drawn from position 2 on segment 1 to position 3 on segment 4 .
