{"version":"1.0","type":"rich","title":"D3 Selection Exploration","description":"This example demonstrates D3’s selection and data-join mechanisms by animating a set of circles whose count, positions, and radii oscillate over time. It renders in SVG, updating every frame via `setInterval`, and uses `d3.select`, `d3.range`, and the `selection.join()` method to bind changing array data to circle elements. The motion follows sine waves, producing a rhythmic, fluid visual. The code relies on D3 v6, with no external data source or interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38804efe56174d7fa2171baebe6f80a0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
