{"version":"1.0","type":"rich","title":"D3 Selection Exploration","description":"This animation demonstrates D3’s data-join pattern by continuously updating a series of colored circles and connecting lines. Each frame, `setInterval` regenerates data with changing positions, radii, and counts, while `selection.data().join()` efficiently creates or updates circles and lines. The SVG uses `selectAll` and `enter/update/exit` behavior, with colors assigned cyclically via a helper function. The example highlights D3’s declarative binding of data to visual elements, using the `vizData` function to apply dynamic geometry and stroke styles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/df603f65789b415eaafbf8975809161f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
