{"version":"1.0","type":"rich","title":"Balls at random : Jul 29,2021","description":"One hundred circles, each filled with a red-to-blue linear gradient, animate randomly across a black SVG canvas over five seconds. The visualization demonstrates basic D3 v6 selection, data binding, and transition methods, using `d3.select` to append an SVG and `transition().duration()` to move each circle’s `cx` and `cy` attributes. The circles, with a radius of 20 and 80% opacity, also receive a gradient stroke via the `url(#svgGradient)` reference. No external data is involved; positions are generated from `Math.random()` multiplied by each index.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd146c219cfc49e4b3e0b5986bc83e3a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
