{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst visualization displays a hierarchical dataset of energy and capital categories, allowing users to click arcs to focus on a child node and its descendants or click the center circle to zoom back out. Rendered as an SVG using D3 v5, the chart uses `d3.partition`, `d3.hierarchy`, `d3.arc`, and a color scale based on `d3.interpolateRainbow`. Transitions between zoom levels are animated via `transition.attrTween` and `d3.interpolate`, with labels and arcs fading based on visibility. The data originates from the Observable `@observablehq/flare` dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c4f4af8882a47f59942761a666ba631?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
