A pie chart displays the top 10 countries' deaths in 2020 attributed to air pollution, using data from a CSV file. Each slice's size corresponds to a country's sales value, with values and a legend on the right. The visualization is rendered as SVG using D3.js v5, leveraging `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` for coloring. The data is fetched asynchronously with `d3.csv`, and the chart is positioned at a center point with a static legend.
