{"version":"1.0","type":"rich","title":" Circles with D3 and React","description":"The visualization displays fourteen circles of varying radii and colors positioned across a 960-by-500 SVG canvas, with each circle’s center, size, and fill defined by a static array of objects. Built with React 19 and D3 v7, the app uses a `useRef` hook to select the SVG element and applies a D3 `select` and `.join` operation to bind the data array to circle elements. The code sets each circle’s `cx`, `cy`, `r`, and `fill` attributes directly from the data source, showing a straightforward declarative mapping of data to SVG shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1bd16f1e18474a05b1243249143d481a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
