A horizontal bar chart displays the ten most populous countries, with population values multiplied by one thousand from a CSV file. Each country’s bar length is proportional to its population, using D3’s `scaleLinear` for the x-axis and `scaleBand` for the y-axis. The visualization renders as an SVG, leverages `axisBottom` and `axisLeft` for tick labels, and styles bars with steelblue fill via CSS.
