This pie chart visualizes the top 10 countries by deaths from air pollution in 2020, with each slice labeled with its value in thousands and accompanied by a legend listing country names and corresponding figures. The visualization uses D3.js v5 with an SVG rendering, employing the `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` APIs to generate the chart from CSV data fetched via `d3.csv`. The code maps death counts to a categorical color scheme and appends text labels and legend elements directly to the SVG.
