This example displays a horizontal bar chart ranking the ten most populous countries in 2020, with bars extending rightward from labeled country names. The visualization uses React to render SVG elements, with D3’s `scaleBand` and `scaleLinear` handling layout and the `format` function abbreviating population values on the x-axis. Data is loaded via D3’s `csv` utility from a UN population dataset, and each bar includes a native SVG `<title>` element for tooltips.
