{"version":"1.0","type":"rich","title":"Fork of Mathematical Graphic Patterns","description":"This animated canvas visualization generates a shifting spiral of colored circles that expands outward in a grid-like pattern. The animation continuously updates using `requestAnimationFrame`, with each circle’s position and radius computed from trigonometric functions of grid coordinates and a slowly advancing time variable. Colors derive from sine-based RGB values, while a semi-transparent black overlay creates a fading trail effect. The code relies solely on the Canvas 2D API, using `getContext('2d')`, `arc`, and `fillRect`, with no external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6fdc338351f43a8868689703f4de78b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
