This example shows a horizontal bar chart of UN population data for 2000, loading the top 10 countries from a CSV file. The chart uses React state management to fetch and store the data, then renders SVG rectangles positioned with `d3.scaleBand` and sized with `d3.scaleLinear`. The `d3.csv` function parses the remote dataset, and React's `useEffect` and `useState` hooks handle asynchronous loading and display a loading message before the chart appears.
