{"version":"1.0","type":"rich","title":"D3 Selection exploration","description":"Animated D3 visualization explores circle selection and layout updates as data changes over time. It renders a dynamic set of circles whose positions, radii, and count oscillate sinusoidally, driven by a timer that updates every frame. The implementation uses D3's `select` API to append an SVG, the `range` utility to generate data, and the `selection.join` method to efficiently synchronize the SVG circle elements with the incoming data. The data is created procedurally in `makeData`, with coordinates and radii derived from sine functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e36847d707c049a4b8d1896b25ff5546?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
