This visualization displays the top 10 countries by deaths in 2020 attributed to air pollution, using a pie chart with colored sections and an accompanying legend. The chart is rendered as an SVG using d3 v5, with data fetched from a CSV via `d3.csv` and parsed. The code uses `d3.pie` and `d3.arc` to generate segments, `d3.scaleOrdinal` for color mapping, and `d3.format` for tick labels showing death counts in thousands. Each slice includes a label and the legend pairs country names with values.
