A horizontal bar chart displays the populations of twenty countries in 2010, sourced from a CSV file. The visualization uses React components with D3 v5 scales and SVG rendering, employing `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. A bottom axis formats tick labels using D3's `format` function, while each bar includes a native SVG `<title>` element for tooltips.
