This bar chart displays the ten most populous countries in the world, with each bar’s length representing a country’s population. It uses d3.csv to load the data and d3.scaleBand and d3.scaleLinear to map countries and populations to screen positions. Customized d3.axisBottom and d3.axisLeft render gridlines and formatted tick labels, while axis titles and tick styling are applied via CSS. The SVG output is built using D3 selections, with population values converted from thousands to raw numbers.
