This example shows a bar chart of the ten most populous countries in 2020, using data loaded from a CSV file hosted on GitHub. The chart renders as SVG rectangles scaled with `scaleLinear` for population values and `scaleBand` for country names. React manages the component state through `useState` and `useEffect`, while D3’s `csv` utility parses the remote data. The visualization demonstrates a clean separation between D3’s data-loading and scaling functions and React’s declarative rendering of SVG elements.
