{"version":"1.0","type":"rich","title":"sunburst chart","description":"This sunburst chart visualizes CO₂ emissions by country from the Global Data dataset, using a hierarchical radial layout with arcs representing regions (Eastern Asia, Northern America, Southern Asia) and their constituent countries. The chart employs D3’s `partition`, `hierarchy`, and `arc` APIs alongside `scaleOrdinal` with `schemeCategory10` and `schemePastel1` for color encoding. Hover tooltips, implemented via SVG `<title>` elements, display each country’s emission value. Rendering is performed with SVG, and the code is structured as a reusable `main` function that appends the chart and legend to a container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bade14785d6f4da981458cc57fa34dac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
