This visualization displays the top 10 countries by deaths from air pollution in 2020, using a pie chart with color-coded segments and accompanying legends. The chart renders death counts in thousands on each slice and lists each country with its corresponding value in a legend panel. The code fetches CSV data via d3.csv, then uses d3.pie, d3.arc, and d3.scaleOrdinal to generate the SVG paths and text labels. Legend elements are manually appended with SVG rect and text elements, with axis formatting handled through d3.format.
