{"version":"1.0","type":"rich","title":"D3 Selection animation exercise","description":"Fifteen circles oscillate in a sine wave pattern across the screen, with each circle’s radius enlarging as it descends and shrinks as it rises. The animation runs on a 60fps interval, updating positions based on time and index. Built with D3 v7, it uses `select`, `range`, and `join` to bind freshly generated data to SVG circle elements each frame.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/820c806f92bb49029f75bc75b64a7dcf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
