{"version":"1.0","type":"rich","title":"D3 Test","description":"Fifteen circles with dynamically changing radii, positions, and colors pulse in a smooth, endless animation, driven by sine-wave values generated in the `makeData` function. The example uses the D3 library (v7.8.5) with its `select`, `range`, and data-join `join` pattern to render SVG circles directly to the document body. Animation runs via `setInterval` at roughly 60 frames per second, updating a time parameter that alters each circle’s `r`, `cx`, `cy`, and `fill` attributes. The visualization demonstrates real-time data binding and SVG attribute updates with a minimal, dependency-light setup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/883e4ac2b5e74f76b749167f57bbc95f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
