{"version":"1.0","type":"rich","title":"Experiments with Rotating Nested Circles","description":"This visualization renders a hierarchical JSON dataset as 300 rotating, nested circles that are projected onto the screen using a custom 3D-to-2D perspective transform with a tilt angle. The circles, representing packed hierarchy nodes via `d3.hierarchy` and `d3.pack`, are drawn as SVG ellipse paths, with each layer rotated slightly to create a depth illusion. Vivid colors highlight specific depth-2 nodes and their descendants, which are computed by sorting and filtering the pack layout. The rendering uses plain SVG with `createElementNS` and D3's array methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5652bf94829b45708fa4beb8c15db0f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
