This example shows a horizontal bar chart of the top 10 countries by 2020 population, rendered as SVG. It demonstrates loading CSV data with `d3.csv` and managing the asynchronous result through React’s `useState` and `useEffect` hooks. The chart uses `scaleBand` for the y-axis and `scaleLinear` for the x-axis, with `max` calculating the domain. A loading state is displayed until the data arrives from the provided UN Population CSV URL.
