Lined up circle, n points Draw lines between every pair of distinct points for n points arranged in a circle, producing something like the below result. Shortest code (in bytes) wins! Your lines don't have to be transparent, but it looks better that way. The output must be a vector graphic, or be an image at least 600 pixels by 600 pixels (either saved to a file or displayed on the screen). To complete the challenge you must draw at least 20.

Looks like this only fails to give a circular embedding for n=4, but the question states n&gt;=20
