This bar chart displays the top 10 most populous countries using data from the United Nations World Population Prospects 2019. The visualization ranks countries along a horizontal axis by their 2020 population estimates, with a teal color scheme and Poppins font. Built with React and rendered as SVG, the chart uses d3.scaleBand for the categorical y-axis, d3.scaleLinear for the quantitative x-axis, and the d3.csv loader to fetch and parse the data. Axis components generate tick marks, while tooltips appear via SVG title elements.
