{"version":"1.0","type":"rich","title":"Fork of practice_with_h","description":"This example demonstrates a circular packing visualization that animates between two views of multi-group data, switching every two seconds between total counts and percentage responses. Circle radii and positions smoothly transition using D3's transition API with a 200-millisecond duration and linear easing, while group labels remain centered within each circle. The visualization is built with D3 v7, using the d3.pack layout algorithm to arrange nodes as non-overlapping circles, and SVG rendering with CSS hover effects. A JavaScript timer toggles the data metric, causing the packing to recalculate and animate the updated positions and sizes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9243796c8aca4ed0b2fea4146fe884d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
