A bar chart displays the population of the top ten most populous countries, with horizontal bars sorted by value. The chart customizes its axes by removing the y-axis line and ticks, adding a custom x-axis label, and formatting tick labels with abbreviations like "1.41B" using d3.format. Built with d3.scaleBand and d3.scaleLinear, the SVG uses d3.axisBottom and d3.axisLeft, with styling applied via CSS classes. Data comes from a local CSV file, loaded with d3.csv and processed to multiply population values by 1000.
