This pie chart visualizes the top 10 countries by deaths from air pollution in 2020, with each slice labeled with its death count in thousands. The chart uses D3 v5’s `pie`, `arc`, and `scaleOrdinal` APIs to generate the SVG segments and legend. Data is loaded asynchronously from a CSV file via `d3.csv`, and the legend lists each country alongside its corresponding value, rendered in a static SVG canvas.
