This scatter plot displays the top 10 most populous countries using a horizontal bar chart, with each bar’s length representing population size. The visualization is built with React and rendered as SVG, using d3.scaleBand for the categorical y-axis and d3.scaleLinear for the quantitative x-axis. Data comes from the United Nations World Population Prospects 2019, loaded via d3.csv. The bars include tooltips showing formatted population values, and axes are styled with light gray ticks and labels.
