This bar chart displays population estimates for ten countries, with the United States, India, and China leading in size. Built with D3 v6, the visualization uses `scaleLinear` and `scaleBand` to map population values to bar widths and country names to vertical positions, respectively. The chart is rendered as SVG within an HTML page, with axes created using `axisLeft` and `axisBottom`. Data is loaded from a CSV file and formatted by multiplying population values by 1,000 before rendering.
