{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This interactive visualization presents a hierarchical sunburst chart of the Flare software project’s package structure. Clicking any arc zooms into that subtree, animating the radial layout with smooth transitions. Built with D3 v5, it uses `d3.partition` and `d3.arc` to compute and draw the arcs, with `transition.attrTween` handling the zoom animation. Colors derive from a `d3.scaleOrdinal` with an interpolated rainbow palette, while labels rotate and reposition via `labelTransform`. Data loads from the @observablehq/flare module.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b98bcd91a2a64eb39c9540e5f787af92?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
