{"version":"1.0","type":"rich","title":"Final Circle Packing","description":"This interactive circle packing visualization renders a hierarchical medical dataset using D3.js v4, fetching JSON data from external URLs. The visualization displays nested circles colored along a linear hue scale, where users can search for specific nodes via an autocomplete search bar. The code uses `d3.hierarchy` and `d3.pack` for layout computation, with SVG circles representing hierarchy levels. Clicking a node displays its ancestor path, while hover states highlight nodes. The implementation includes a tooltip system for additional node information, all rendered through D3's selection and rendering API within an SVG container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/537ce62314b54241ab6884ebc8e5a084?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
