{"version":"1.0","type":"rich","title":"Mathematical Graphic Patterns","description":"This animated canvas visualization displays a grid of circles that ripple outward in concentric, rotating patterns resembling a living mathematical kaleidoscope. The code, written by hotdoujiang, generates each circle’s position and radius using trigonometric functions of a continuously incrementing `time` variable, while colors shift through an RGB spectrum based on grid coordinates. The rendering uses the raw Canvas 2D API with `fillRect` to create a fading trail effect and `arc` calls to draw individual circles. The pattern adapts to the window size, recalculating dimensions and offsets as the browser resizes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fe459784aeef4e1cb038f7352b185dfb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
