This bar chart displays the population of ten countries in the year 2000, with bar lengths proportional to population values and country names listed along the vertical axis. The visualization uses React components with D3 v5’s `scaleBand` and `scaleLinear` for positioning, `csv` for data loading from a GitHub-hosted CSV, and `format` for abbreviating tick labels (e.g., replacing “G” with “B”). SVG rectangles render the bars, and each bar includes a native `<title>` tooltip showing the formatted population value. The axes are drawn with custom components, and the chart is framed by margins with a labeled x-axis.
