This example displays a horizontal bar chart of the top 10 countries by population in 2020. The view encodes population values as bar lengths using `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the categorical country labels on the y-axis. Data loads asynchronously from a CSV via `d3.csv`, with React’s `useState` and `useEffect` managing the fetching and rendering cycle. The SVG output respects a fixed margin convention by translating a `<g>` element to offset the chart area.
