This bar chart displays population estimates for the ten most populous countries, using horizontal bars ordered alphabetically by country name. The visualization loads data from a CSV file and renders SVG rectangles scaled by population magnitude. Built with D3 v5, the code uses `d3.csv`, `scaleBand`, `scaleLinear`, `axisLeft`, and `axisBottom` to construct the chart with labeled axes and steel-blue bars. Margins, a custom inner plotting area, and a 0.1 band padding define the layout.
