This bar chart visualizes the population of the top 10 most populous countries, using 2019 estimates from the United Nations World Population Prospectus. The chart displays population on a linear scale along the x-axis and country names on a band scale along the y-axis, with each bar colored steel blue. Built with D3 v5, it uses `d3.csv` to load data, `scaleLinear` and `scaleBand` for scaling, and `axisLeft` and `axisBottom` for labeled axes. The SVG rendering includes margin-based layout and implied padding between bars.
