This example displays a pie chart of the top 10 countries by 2022 population, with all remaining countries aggregated into an “Others” slice. Using d3.pie and d3.arc, it generates the chart from CSV data fetched via d3.csv, processes and sorts the dataset, and renders SVG paths with colors from d3.scaleOrdinal and schemeCategory10. A legend is drawn beside the chart using d3.selectAll and attribute transforms.
