This visualization shows the top 10 countries by population in the year 2000 as horizontal bars, with country names on the y-axis and population values on the x-axis. It is built with React and D3 v5, using `scaleBand` and `scaleLinear` to position the marks. The SVG rectangles render the data, which is loaded via `csv` from a GitHub-hosted dataset, and tooltips display formatted population values using D3’s `format`. The custom `AxisBottom` and `AxisLeft` components generate the tick marks and labels.
