{"version":"1.0","type":"rich","title":"Sine Wave Circles Playground","description":"A grid of 300 white circles forms a static horizontal row that animates vertically as a sine wave, creating a fluid, undulating pattern across a black background. The animation uses D3 v7's `d3.timer` to continuously update each circle's `cy` attribute based on the sine of its index and elapsed time. Written in ES6 and ported from an older bl.ocks.org example, this SVG-based playground demonstrates how math functions can drive simple shapes into organic motion.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
