This visualization shows the top 10 countries by deaths from air pollution in 2020 using a pie chart, with each slice labeled by its death count in thousands and accompanied by a color-coded legend. The chart is built with D3 v5, using the `d3.pie` generator to compute angles and `d3.arc` to render the segments, while `d3.scaleOrdinal` assigns SLice colors. Data is loaded as CSV from a gist URL, with text labels positioned using `arcGenerator.centroid`. The legend displays country names and values in a separate SVG group.
