This D3.js bar chart displays population figures for ten countries, ordered alphabetically along the vertical axis with horizontal bars scaled by population. It uses `d3.csv` to load the data, `d3.scaleLinear` and `d3.scaleBand` for positioning, and `d3.axisLeft` and `d3.axisBottom` to render the axes. The SVG chart appends rectangles with heights based on band width and fills them with steelblue.
