This example shows a horizontal bar chart that ranks ten countries by their population in the year 2000, using a green fill and tooltips that format values with a "B" suffix. The React-based visualization relies on D3’s `scaleBand` and `scaleLinear` for axes, and builds the SVG from `<rect>` marks, with custom `AxisBottom` and `AxisLeft` components rendering tick lines and labels. Population data is loaded via `d3.csv` from a GitHub-hosted dataset. Blue gridlines and Poppins typography style the chart, which is rendered entirely as SVG.
