{"version":"1.0","type":"rich","title":"D3 Transitions","description":"Six colored circles of varying sizes move across a light green canvas, growing from and shrinking to a radius of zero at different speeds. The visualization demonstrates the D3 transition API, using a slow two-second transition to animate the circles' entry and exit by scaling their radius, while a fast 500-millisecond linear ease animates position updates. The sketch initializes six data points with id, x, y, r, and fill attributes, then uses D3's `select`, `transition`, and `easeLinear` functions to orchestrate the dynamic reshaping of the circle group. A video embed links to a YouTube demonstration of the transition effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2620ff1c80eb4f089136b0ecf0974a1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
