This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization encodes country names on a band scale and population values on a linear scale, with steel-blue rectangles representing each value. Built with D3 v5, the code uses `csv` for data loading, `scaleBand` and `scaleLinear` for scales, and `axisLeft` and `axisBottom` for axes. SVG rendering is used throughout, with margins creating an inner plotting area for the chart elements.
