A horizontal bar chart ranks the ten most populous countries in the year 2000, showing each country’s population as a blue bar. Built with React and D3 v5, the visualization uses `scaleLinear` and `scaleBand` for positioning, while CSV data is loaded via the `useData` hook. Custom `AxisBottom` and `AxisLeft` components render tick marks, and hover tooltips display exact population values through SVG `<title>` elements.
