This bar chart shows the population of the ten most populous countries using 2018 estimates from the United Nations World Population Prospects. The visualization displays horizontal bars ordered by country names, with population values on the x-axis. It uses D3 v5 APIs including `d3.csv`, `d3.scaleLinear`, `d3.scaleBand`, `d3.axisLeft`, and `d3.axisBottom` to load data, scale ranges, and render axes. The chart is rendered as an SVG with steelblue rectangles and includes a title, with data parsed from a CSV file.
