This example displays a horizontal bar chart of the ten most populous countries for the year 2000, using data fetched from a remote CSV file hosted on GitHub. React's `useState` and `useEffect` hooks manage the asynchronous data loading, showing a "Loading" message until the data arrives. The bars render as SVG `<rect>` elements, with positions and lengths scaled using D3's `scaleBand` and `scaleLinear` functions from `d3`. The visualization demonstrates the integration of React for state management and D3 for data-driven scaling.
