A horizontal bar chart displays population figures for ten countries in 2000, with bars extending from a shared left axis and length-encoded values along a linear scale. Data loads from a CSV file through D3’s `csv` API, and the visualization renders as an SVG using React components. D3’s `scaleBand` positions the categorical y-axis, while `scaleLinear` maps population values to x-axis coordinates. Axis tick lines appear in blue, and bar lengths provide direct comparison of relative population sizes.
