This example shows a horizontal bar chart of country populations for 2022, displaying the top ten countries sorted by their population values. Built with React and D3, it renders SVG rectangles whose lengths are scaled using `d3.scaleLinear` and positioned with `d3.scaleBand`. The chart loads CSV data via `d3.csv` and uses React’s `useState` and `useLayoutEffect` to fetch and update the data, with the final visualization drawn inside an SVG element sized to the browser window.
