A horizontal bar chart displays population figures for nine countries, using data from a CSV file. The chart ranks countries by population along a linear scale, with country names on a band scale for bar positioning. Built with D3 v6, the visualization loads CSV data, converts population values to numbers, and renders SVG rectangles. It uses `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the axes and bars, with steelblue fills and margins for layout.
