This bar chart displays the populations of the top 10 most populous countries, based on 2018 estimates from World Population Prospects 2017, with values shown in thousands. It uses d3.scaleLinear for the horizontal population axis and d3.scaleBand for the vertical country categories, rendering SVG rectangles via a data join. Axes are drawn with d3.axisLeft and d3.axisBottom, and the chart applies margins to position the visualization within a 960×500 SVG canvas.
