A horizontal bar chart displays population figures for ten countries in the year 2000, using yellow bars with green tick labels on a red axis grid. Built with React and D3 v5, the visualization loads CSV data via `d3.csv`, scales values with `d3.scaleBand` and `d3.scaleLinear`, and renders SVG rectangles through reusable components. Axis formatting uses `d3.format` to abbreviate large numbers, and tooltips appear via SVG `<title>` elements.
