{"version":"1.0","type":"rich","title":"RV2","description":"This interactive zoomable sunburst diagram visualizes hierarchical data, such as product categories across cities, using a circular layout of nested arcs. Clicking an arc zooms into that subtree, while a central circle returns to the root. Built with D3 v5, it employs `d3.partition` for layout, `d3.arc` for rendering SVG paths, and `d3.interpolate` within `transition.attrTween` for smooth animated updates. Data originates from the `@observablehq/flare` module, fetched via the Observable stdlib’s `require` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4117f7eb117947f39c1bb34d68e886ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
