This bar chart displays the populations of ten countries, sorted from largest to smallest, with China and India leading. The visualization uses D3 v7 with an SVG rendering approach. It employs `d3.scaleLinear` for the population axis, `d3.scaleBand` for country categories, and `d3.axisLeft` and `d3.axisBottom` to render the axes. Data loads from a CSV file via `d3.csv`, with population values converted from thousands to absolute numbers.
