This bar chart displays the 2018 population estimates for the top 10 most populous countries, based on data from the United Nations World Population Prospects. It uses D3 v5 with `d3.csv` and `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the quantitative x-axis. The chart renders as an SVG, with axes generated via `d3.axisLeft` and `d3.axisBottom`, and rectangular bars colored steelblue. Population values are read from data.csv and multiplied by 1,000 to reflect actual counts.
