This example shows the population of the top 10 most populous countries as horizontal bars, sorted in descending order. The chart uses React to render SVG elements, with d3-scale for creating the linear x- and band y-scales, and d3-format to abbreviate tick labels (e.g., converting billions to “B”). Data is loaded asynchronously from a CSV file using d3.csv, and a tooltip appears on each bar via an SVG `<title>` element. The visualization demonstrates a clean, minimal styling with custom font and color choices.
