{"version":"1.0","type":"rich","title":"Happiness Report Pie Chart","description":"This pie chart visualizes the distribution of happiness scores across global regions, using data from the 2015 Happiness Report. The chart aggregates scores by region and displays each region as a colored slice with labels. Built with D3 v6, the visualization uses `d3.pie`, `d3.arc`, and `d3.rollup` to process and render the data, while `d3.scaleOrdinal` and `d3.schemeCategory10` assign colors. A legend maps regions to their corresponding hues, and the SVG output includes a clean, styled interface.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a651c10e78142d6ae720bf86fea02bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
