{"version":"1.0","type":"rich","title":"Fork of Circles with D3.","description":"This example demonstrates how to create and position seven filled circles within an SVG element using D3.js v7, with each circle’s coordinates, radius, and color defined in a plain JavaScript data array. The visualization initializes a single SVG that adapts to its container’s dimensions, then applies the D3 general update pattern via `select`, `data`, and `join` to bind the array to circle elements. Method chaining sets the `cx`, `cy`, `r`, and `fill` attributes for each circle, while a shared opacity value adds visual layering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8de3d42100c947b89ebb138b7770854c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
