{"version":"1.0","type":"rich","title":"Untitled","description":"A vertical column of 50 circles animates across an SVG canvas, cycling horizontally in a loop. The circles are colored along a dark-to-light scale using `d3.scaleLinear` with HSL interpolation, creating subtle banding. D3 v4 selects the SVG, appends the circles, and chains `transition` calls with staggered `delay` and recursive `on(\"start\", repeat)` to move each circle from left to right and back, demonstrating fundamental DOM manipulation and animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b75445e39604fd9a4a064a31b1ffe93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
