This example displays the top 10 most populous countries as horizontal bars without any axes, using raw SVG rectangles. The app loads United Nations population data from a CSV file, sorts it by 2020 figures, and maps country names to a d3.scaleBand for vertical positioning while a d3.scaleLinear scales bar widths. Built with React hooks (useState, useEffect), it fetches the dataset asynchronously via d3.csv. The chart intentionally lacks labels, ticks, or a scale, presenting only the relative lengths of bars to compare population sizes.
