This pie chart displays the top 10 most populated countries in the world based on 2022 population data loaded from a GitHub gist via d3.csv. The visualization uses d3.pie and d3.arc to generate SVG path segments, with colors assigned through d3.scaleOrdinal. A custom legend, built with SVG circles and text, shows each country name alongside its population value formatted with d3.format, while the chart is centered using an SVG group transform.
