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 demonstrates custom axis styling, including tick labels, grid lines, and axis titles. Built with D3 v5, the code uses `scaleLinear` for the x-axis and `scaleBand` for the y-axis, with SVG rendering. It reads data from a CSV file and applies custom fonts and colors to enhance the chart’s readability.
