The chart displays a horizontal bar ranking of the top 10 most populous countries, with population values converted from thousands to raw counts and formatted as abbreviated labels using `format('.3s')`. The visualization uses D3 v5 APIs including `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, rendering as SVG. Data is loaded from a CSV file, with bars styled via CSS and the y-axis gridlines removed.
