This example displays a horizontal bar chart of the top 10 countries by population for 2020, loaded from a CSV file via `d3.csv`. The visualization uses React with hooks (`useState`, `useEffect`) to manage the asynchronous data loading and render the SVG. D3’s `scaleBand` and `scaleLinear` position the bars and axes, while gridlines and tick labels are generated using `xScale.ticks()`. The chart is drawn inside an SVG with explicit margins, and text elements for the country labels are styled with a blue stroke.
