This bar chart ranks the top 10 most populous countries according to the 2018 United Nations World Population Prospects, with each bar representing population in thousands. The visualization uses D3 v5, leveraging `scaleLinear` and `scaleBand` to map numeric and categorical axes, and `axisLeft` and `axisBottom` for chart ticks. It renders as SVG, with bars styled in steelblue and readable font sizes.
