This pie chart visualizes the top 10 countries by deaths attributed to air pollution in 2020, using a color-coded legend and percentage-like labels. The visualization is built with D3.js v5, leveraging `d3.pie` and `d3.arc` to generate the chart’s segments, while `d3.scaleOrdinal` maps colors to data categories. Data is fetched asynchronously via `d3.csv` from a remote URL, and the SVG rendering includes interactive text labels and a legend. The chart encodes death counts in thousands, with each slice proportionally representing the data.
