{"version":"1.0","type":"rich","title":"Illusion of rain","description":"A grid of small circles falls steadily down the canvas like rain, while a separate set of static grey circles and one gold circle sit in the upper region as a backdrop. The rain effect is animated with a Canvas 2D context, using `requestAnimationFrame` and `Math.sin` to oscillate each dot’s horizontal position and size. The drop size toggles between blue and light blue fills based on a sine threshold. The SVG defines the fixed circles, and the JavaScript loop redraws the moving grid each frame.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/be2a0240bbc547749b6a8e5912cea4d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
