This pie chart displays the top 10 most populated cities in the world based on 2022 population data. Each slice represents a city’s total population, with a color-coded legend showing city names and values in thousands. The visualization uses D3 v5’s `pie` and `arc` generators to compute angular segments, with `scaleOrdinal` mapping colors to population values. Data is loaded asynchronously from a CSV file via the `csv` function, and the SVG rendering includes custom legend text and percentage formatting using `format`.
