{"version":"1.0","type":"rich","title":"Question 1","description":"This example shows the top 10 countries by deaths from air pollution in 2020 as a donut-style pie chart. Each slice is labeled with its death count in thousands, and a legend lists the countries with corresponding color swatches and values. Built with D3.js v5, the code uses `d3.pie`, `d3.arc`, `d3.scaleOrdinal`, and `d3.format` to compute and render the chart as SVG. Data is fetched as CSV from a GitHub repository, with sections colored via a fixed array of ten colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bc6761414a02493890280099a5fac643?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
