{"version":"1.0","type":"rich","title":"Co2 Emissions Sunburst chart - Top 3 Regions","description":"This sunburst chart visualizes the top three regions by total CO₂ emissions, with each ring segment representing a country within those regions. The size of each arc corresponds to a country’s emissions value, while a warm-to-cool sequential color scale (using `scaleSequential` and `interpolateWarm`) reflects the total emissions range. The visualization is built with D3’s `hierarchy`, `partition`, and `arc` APIs, starting from a dataset grouped by region and filtered to the highest emitters. Hovering over a segment highlights it with a black border and displays the country name and rounded emissions value as temporary text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0d318f227b304d70b1dff98fdbccf9e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
