This pie chart visualizes the top 10 countries by deaths from air pollution in 2020, with each slice labeled with the death count in thousands and accompanied by a color-coded legend listing country names and values. The visualization loads CSV data and uses D3 v5’s `pie`, `arc`, `scaleOrdinal`, and `select` APIs to generate SVG paths and text labels. Slices use a fixed color palette and centroid-based text positioning via `arcGenerator.centroid`. The legend is built with appended SVG rectangles and text elements, highlighting the data source from a GitHub-hosted CSV file.
