{"version":"1.0","type":"rich","title":"Sunburst","description":"A zoomable sunburst chart visualizes the hierarchical flare dataset, showing nested categories as concentric rings where each arc's angular width represents its value. The visualization collapses or expands levels when a user clicks on an arc or the central circle, with smooth transitions animating the radial layout. Built with D3 v5, the code uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while `transition.attrTween` and `d3.interpolate` animate arc geometry during zoom. The color scale uses `d3.scaleOrdinal` and `d3.interpolateRainbow`, and data loads asynchronously via the Observable `require` API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ebaf2dd8cb434b3499a91bdf0fb35eb4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
