This bar chart displays the populations of ten countries, using horizontal bars ordered from largest to smallest. The visualization loads data from a CSV file using `d3.csv` and renders it as SVG. The code employs `d3.scaleLinear` for the x-axis population values and `d3.scaleBand` for the categorical y-axis, while axes are generated with `d3.axisLeft` and `d3.axisBottom`. Population numbers are converted from integers with a thousand multiplier before scaling.
