{"version":"1.0","type":"rich","title":"Fork of Sine Wave Circles","description":"A uniform field of 300 white circles on a black background forms a horizontal sine wave that undulates vertically over time. The animation is driven by a `d3.timer` callback, which updates each circle’s `cy` attribute using its index and elapsed time inside a `Math.sin` expression. The D3 code uses `selectAll`, `data`, `enter`, and `append` to create the SVG circles, with `cx` and `r` derived from the total width and circle count. This example is a port of a classic p5.js math demonstration, implemented for D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fd828f337972414f895806d67f9f5c8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
