This bar chart displays population figures for the ten most populous countries, with horizontal bars ordered from largest to smallest population. The visualization uses D3.js v7 to load CSV data via `d3.csv`, scales the values with `d3.scaleLinear` and `d3.scaleBand`, and renders the chart as SVG elements. Axes are generated using `d3.axisLeft` and `d3.axisBottom`, while population values are multiplied by 1,000 during data preprocessing.
