This example shows a horizontal bar chart of the top 10 most populous countries, using the 2020 population data from a CSV file hosted on GitHub. The chart is rendered as an SVG, with a React component managing the data loading and state via `useState` and `useEffect`. D3’s `scaleBand` and `scaleLinear` map the data to bar positions and widths, while a margin object defines the inner plotting area, ensuring the bars are offset from the SVG edges via a translated `<g>` element.
