This bar chart displays the population in 2000 for the ten most populous countries, sorted in descending order. The visualization uses D3 v7 to load CSV data via `d3.csv` with `autoType`, and renders horizontal bars with `d3.scaleBand` for the y-axis and `d3.scaleLinear` for the x-axis. The axes are drawn using `d3.axisLeft` and `d3.axisBottom`, with tick labels formatted using `d3.format('~s')`. The SVG output is styled with Poppins font and palegreen bars.
