This pie chart visualizes deaths in 2020 attributed to air pollution by country. Each colored slice represents a nation’s death count, with labels showing values in thousands. A legend lists countries alongside their corresponding colors and totals. Built with D3 v5, it uses `d3.pie`, `d3.arc`, and `scaleOrdinal` to generate SVG paths, while data is loaded from a CSV using `d3.csv` and styled via CSS.
