This pie chart visualizes the top 10 car-producing countries in the world based on 2019 data. It displays the total production value for each country as a proportional slice, with a legend identifying each country by name and value. The chart uses D3.v5’s `pie`, `arc`, and `scaleOrdinal` APIs to compute and render the SVG segments. Data is loaded from a CSV file via `d3.csv`, and the chart is positioned using `svg.append` with a translate transform. Colors are assigned from a custom range, and legend values are formatted using `d3.format`.
