This bar chart displays population estimates for the ten most populous countries, using horizontal bars ordered by descending population. The visualization is built with D3 v5, loading data from a CSV file and rendering to SVG. It employs `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the categorical y-axis, and `d3.axisLeft` and `d3.axisBottom` for the axes. The chart maps population values to bar widths, with the y-axis labels showing country names.
