This example displays a horizontal bar chart of the top 10 most populous countries, with country names on the y-axis and population values on the x-axis. The visualization uses React to manage state and render SVG elements, while D3 provides the `csv` data loading, `scaleBand` and `scaleLinear` for scales, and `max` for domain calculation. Population data is sourced from a CSV file, and each bar’s width encodes the 2019 population value, with grid lines and tick labels generated from D3’s scale ticks.
