Inspiration: The limit of a regular n-gon as n → ∞ is a circle.
Description: In the physical world, a perfect circle does not exist and cannot be drawn. In the world of pixels and perception, however, there is some point at which our eyes no longer discern the n-gon. I think, for this graphic, I see a circle around the 85-gon and up. Very dependent on size, canvas resolution, widths, color etc. Zooming in, the illusion breaks down even at the hectogon (100-gon). Was also fun familiarizing myself with some of these unusual names for regular polygons : )
