{"version":"1.0","type":"rich","title":"Activity 7 Pie Chart","description":"This pie chart visualizes the Happiness Dataset, showing the happiness scores of the top 20 countries with all remaining countries aggregated into an \"Others\" slice. D3's `pie` and `arc` generators create the SVG slices, while `scaleOrdinal` with `schemeCategory10` assigns colors, and a custom legend is drawn alongside. The data is loaded asynchronously via D3's `csv` method from a GitHub gist, with the `processData` function sorting and aggregating scores before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/19c60339d7a0487d83309ed17588948b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
