This visualization shows the top 10 car-producing countries in the world, with each country’s 2019 total vehicle output represented as a proportional slice of a pie chart. The data is loaded from a CSV file via `d3.csv` and parsed asynchronously, with values summed from the year 2019. The chart is rendered using D3 v5’s `pie()` and `arc()` generators to compute segment angles, with `scaleOrdinal` providing a fixed color palette for each country. SVG elements, including the pie slices, a legend with colored circles, and formatted text labels using `d3.format`, are appended and positioned manually within the main SVG container.
