31:T645,# Random polygons with circle packing In principle, it is easy to generate random polygons, but the idea here is to generate "interesting" polygons. This is hard to define, but here are a few criteria about what an "interesting" polygon should look like 1. It should have some waviness, but not too much. In general, we want non-convex polygons. 2. Angles should be constrained to a reasonable range in order to avoid angles that are too acute or too obtuse. 3. Similarly, it should have variable side lengths, but not too much. 4. It should cover some reasonable area with respect to its perimeter. In other words, it should not be too skinny. 5. It should not be self intersecting. 6. It should have a given number of sides. Given that, the algorithm used in this notebook consists of creating a force simulation between balls having sizes according to the desired edge variability. They are initially placed around a circle big enough to accommodate all balls side by side. Link forces are created between neighboring balls to introduce a certain rigidity to this initial circular shape. A number of additional links, what I call "ties", are then created in order to bring together random pairs of balls. Ties can be created carefully in order not to introduce edge crossings. The demo allows you to configure these aspects of the simulation and shows the progress of the simulation until the final form is achieved. At the end of the simulation, polygons are tested for self-intersection and painted red if so. You can also find below a set of 64 random polygons created with the current settings. 32:T62c,{ const size = (width * 9) / 16; const canvas = htl.html`
