A horizontal bar chart displays population estimates for ten countries, ranked from China to Mexico. The bars vary in length according to population values, with country names on the y-axis and population counts on the x-axis. Built with D3 v6, the chart uses `scaleLinear` and `scaleBand` for scales, `axisLeft` and `axisBottom` for axes, and SVG rectangles for bars. Data loads from a CSV file via `d3.csv`, with values multiplied by 1,000. Dotted outlines style the bars against a black background.
