{"version":"1.0","type":"rich","title":"My Fork of Circles with D3","description":"This example generates an animated spiral galaxy of 420 circles in SVG using D3 v7. Each circle is positioned at a radius proportional to the square root of its index and an angle based on the golden angle, with colors assigned via `d3.interpolateRainbow`. The circles transition from radius zero to their final size with staggered delays, followed by an infinite sinusoidal pulse animation using `transition.attr`. The visualization is centered in a fixed container with a light green background, rendering purely through D3’s data join and transition APIs in an ES module.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/32425a2ab80f40188af101ac453af61a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
