This stylized bar chart displays the top 10 most populous countries in 2020, ranked from largest to smallest, with population values represented as horizontal bars. The chart uses React to render SVG elements, with d3-scale providing the linear and band scales for positioning, while d3-format converts large population numbers into abbreviated labels like “1.4B.” Data comes from the United Nations World Population Prospects 2019, loaded via d3.csv, and each bar includes a native SVG tooltip showing its exact formatted value.
