This bar chart displays the populations of ten countries, scaled from a CSV dataset. It uses D3 v5’s `scaleLinear` and `scaleBand` to map population values to bar widths and country names to vertical bands, with `axisLeft` and `axisBottom` generating the axes. Bars are rendered as SVG rectangles, with data loaded via `d3.csv` and population values multiplied by 1000 to reflect thousands.
