A stylized bar chart displays the top 10 most populous countries, with population values on the x-axis and country names on the y-axis. Built with React and rendered as SVG, the chart uses D3's `scaleBand` and `scaleLinear` for scales, `format` for tick labels, and `csv` to load United Nations World Population Prospects 2019 data. The Poppins font and a teal color for bars provide the stylized aesthetic, while tooltips show formatted population values on hover.
