{"version":"1.0","type":"rich","title":"Fork of D3 Selection Exploration","description":"This example demonstrates D3 selections and data joins through an animated swarm of circles whose count, position, and size shift continuously over time. It uses `d3.select`, `d3.range`, and `data().join()` to bind an array of simulated points to SVG circle elements, updating their `cx`, `cy`, and `r` attributes in a 60fps `setInterval` loop. The animation responds to a sine-based time variable, creating smooth, organic motion. Rendering happens entirely in SVG within a full-window viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/324e414efe104351901b6a55427ef688?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
