This visualization displays population figures for 20 countries in 2010 as horizontal bars. The chart uses React with D3 v5's `scaleBand` and `scaleLinear` to map countries to vertical bands and population values to bar widths. Rendered as SVG, the code imports data from a GitHub-hosted CSV file and applies D3's `format` function to abbreviate axis tick labels. Blue axis lines, green bars, and a Poppins typeface style the visualization. Native SVG `<title>` elements provide tooltips showing the formatted population value for each bar.
