This simple webapp is inspired by this Mathologer video. It generates diagrams by considering N evenly spaced points around a circle, and connecting point k to the point (k * M) mod N, where M is a multiplier. The diagrams are parameterised by (N, M). The (9, 2) and (7417, 240) diagrams feature in the video. Other really nice ones I've found are (8807, 839) and (2048, 820).
