This bar chart displays the population of ten countries, using horizontal bars sorted by population in descending order. The visualization is built with D3 v5 and rendered as SVG elements. It loads data from a CSV file, converts population values to absolute numbers, and uses `d3.scaleLinear` and `d3.scaleBand` to map values to positions. Axes are added with `d3.axisLeft` and `d3.axisBottom`, while bars are drawn as SVG rectangles.
