This example shows a horizontal bar chart of population figures for 30 countries in 2020, ranked with country names on the y-axis and population values on the x-axis. The visualization uses React components to render SVG elements, with D3 v5’s `scaleBand` and `scaleLinear` for positioning and the `format` function to abbreviate tick labels (e.g., “1.2B”). Data is loaded asynchronously from a CSV file using D3’s `csv` method, and each bar includes a tooltip via the SVG `<title>` element.
