This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects. Each bar’s length encodes population, with countries listed vertically. The visualization uses d3.csv to load the data, d3.scaleLinear for the x-axis, d3.scaleBand for the y-axis, and d3.axisLeft and d3.axisBottom to render axes. Data is drawn as SVG rectangles within a fixed 960×500 viewport, with a steelblue fill defined in CSS.
