{"version":"1.0","type":"rich","title":"Fork of Circles with D3","description":"This example renders a generative spiral of 500 semi-transparent circles that grow and shift in a golden-hued gradient across a pale green canvas. The visualization uses D3 v7’s `select` API and the `.join()` operator to declaratively create and update an SVG, computing each circle’s `cx`, `cy`, `r`, and `fill` from sine and cosine functions of its index. The code demonstrates D3’s modern “join” pattern for idempotent state management, with the container’s dimensions driving the spiral’s center and radius.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a1b021f9c4f4117b7f8e78a8d706d73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
