This bar chart visualizes the top 10 most populous countries using 2019 United Nations World Population Prospects data. It displays horizontal bars colored teal against a clean white background, with population values formatted in billions along the x-axis and country names on the y-axis. Built with React and D3 v5, the visualization uses scaleBand and scaleLinear for axes, while the Marks component renders SVG rect elements with built-in tooltips. The chart omits traditional gridlines and labels, instead employing a minimalist, stylized aesthetic with Poppins typography.
