This example shows the top 10 most populous countries as a horizontal bar chart, with country names on the y-axis and population counts on the x-axis. The visualization is built using React and renders SVG elements, with D3’s `scaleBand` and `scaleLinear` handling the coordinate mappings. Axes are custom components that generate tick marks and labels, while the data is loaded from a CSV file of United Nations World Population Prospects 2019 via D3’s `csv` function.
