This example shows a horizontal bar chart of population data for 20 countries in 2010, sorted by country name along the y-axis with population values on the x-axis. The visualization uses React components to render SVG elements, with D3 v5 scales (`scaleBand` and `scaleLinear`) and formatting utilities. The data is loaded via D3’s `csv` function from a remote gist, and each bar includes a native SVG `<title>` tooltip that displays the formatted population value. The axes are custom components that generate tick marks and labels, with formatting that converts large numbers to abbreviated units like “B” for billions.
