{"version":"1.0","type":"rich","title":"D3-Fuse Demo","description":"The D3-Fuse Demo shows a swarm of 1,200 circles merging into larger clusters as their radii grow and shrink in a repeating animation cycle. Circles with larger areas absorb smaller neighbors, and each merged group displays a color scaled by its final radius. The example uses the D3-Fuse plugin with d3.quadtree for spatial collision detection and d3.interval to trigger periodic rescaling, while SVG circle transitions animate positions and sizes via the parent cluster’s layout coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-0d7b626f4b83429fff94e79e3884ab60?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
