This bar chart displays population estimates for ten countries, with the United Nations World Population Prospects data loaded via `d3.csv` and transformed by multiplying each value by 1000. The visualization uses D3 scales (`d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis) and renders SVG rectangles with an ordinal color scale. Axes are generated with `d3.axisLeft` and `d3.axisBottom`, while the chart is positioned using a margin convention and fixed SVG dimensions.
