{"version":"1.0","type":"rich","title":"fetch D3 v5 Zoomable Sunburst","description":"A zoomable sunburst chart visualizes the hierarchical Flare dataset, showing interactive drill-down and zoom-out navigation across nested categories. Built with D3 v5, this SVG-based example uses d3.partition to lay out nodes as concentric rings, with d3.arc generating the path geometry and d3.scaleOrdinal with an interpolateRainbow palette for color encoding. Clicking a node triggers a smooth transition via transition.attrTween, animating the arc angles to focus on the selected subtree while fading labels based on visibility thresholds.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/45f0b134e8b54f3a8bdce5d74e4b04d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
