This pie chart displays the top 10 countries by deaths from air pollution in 2020, with each slice labeled with its death count in thousands. The chart is rendered using D3.js v5, fetching CSV data from a GitHub gist. It uses d3.pie to compute arc segments, d3.arc to generate path geometry, and d3.scaleOrdinal for color mapping. Slice labels are positioned via arc centroid calculations, while a legend lists countries with their corresponding values and colored swatches. The SVG output is styled with custom CSS for typography.
