{"version":"1.0","type":"rich","title":"ACT_TASK1","description":"This pie chart visualizes the distribution of happiness scores across 20 countries, aggregating all remaining nations into an \"Others\" slice. Built with D3 v6, it uses `d3.pie` and `d3.arc` to generate the segments, `d3.scaleOrdinal` with `schemeCategory10` for coloring, and a custom legend rendering via `d3.select`. The data is loaded through `d3.csv` from a remote Happiness dataset, processed to highlight the top-scoring countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2900b165a4b642efa016c455d9acb66f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
