{"version":"1.0","type":"rich","title":"Planetary Rings","description":"This visualization simulates planetary rings around a rotating Earth using D3 v4. Ten concentric ring paths, each representing the same equatorial feature, are drawn with increasingly zoomed orthographic projections and slightly enlarged clip angles to create a layered, three-dimensional ring effect. The sphere and graticule are rendered via `d3.geoPath` and `d3.geoOrthographic`, while a `d3.timer` animates the rotation by updating projection rotations. Rings use dashed strokes and varied colors, with the code deriving from a rotating orthographic block upgraded to v4.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-cebfc65f309fb1c691ea690722aaa712?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
