{"version":"1.0","type":"rich","title":"Question1","description":"This example shows the distribution of Eurovision Song Contest winners by country from 2000 to 2022, using a pie chart with a legend displaying each country’s win count. The visualization loads CSV data from a GitHub gist, counts wins per country, and renders the chart with D3 v7’s `d3.pie` and `d3.arc` generators. SVG paths are colored via `d3.scaleOrdinal` with the `schemeCategory10` palette, while labels are positioned at arc centroids using `arc.centroid`. A legend is appended as SVG groups with rectangles and text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/21571c10c3b3431db9f669592c8e383a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
