This stylized bar chart displays the top 10 most populous countries using data from the United Nations World Population Prospects 2019. The visualization orders bars horizontally, with population values extending left to right on a linear scale and country names positioned along a categorical band scale. The React-based interface renders SVG elements through reusable AxisBottom, AxisLeft, and Marks components, which rely on d3 scaleLinear, scaleBand, and format APIs to handle scaling and tick labeling. Population figures are converted from raw CSV values using a row parsing function that multiplies the 2020 estimates by 1000.
