{"version":"1.0","type":"rich","title":"Changing Colors with Waves","description":"Rows of circles ripple horizontally across a 960 by 500 pixel canvas, their horizontal positions perturbed by a sine wave and their sizes pulsing with time. Each circle is drawn using the Canvas `arc` and `fill` methods, with its color switching between red and blue depending on whether its current size exceeds a threshold. The animation runs via `requestAnimationFrame`, advancing a time variable `t` in increments of 0.1 to drive the motion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
