This bar chart displays population estimates for ten countries, with population values read from a CSV file and converted from thousands to the raw count. The visualization uses D3 v7's `scaleLinear` and `scaleBand` to map population to bar width and country names to vertical bands, respectively, rendering the result as SVG. Axes are generated with `axisBottom` and `axisLeft`. The bars themselves are styled with a steelblue fill via CSS, and the layout applies fixed margins to position the chart within the SVG canvas.
