A pie chart from d3.v5 displays the top 10 car-producing countries in 2019, using data loaded via `d3.csv` from a GitHub Gist. Each slice’s size corresponds to a country’s total production value, with a color-coded legend listing country names and formatted totals using `d3.format`. The chart is rendered as an SVG, with slices generated using `d3.pie` and `d3.arc`, and legends positioned via `d3.select` and `d3.append`.
