A horizontal bar chart displays population figures for ten countries, with bars ordered by descending value from China to Mexico. The visualization uses D3.js v7 with an SVG rendering approach, loading data from a CSV file via `d3.csv` and scaling populations by 1,000. Axes are generated through `d3.axisLeft` and `d3.axisBottom`, while `d3.scaleLinear` and `d3.scaleBand` position and size the bars. Bars appear in steel blue on a clean, margin-based layout.
