This stylized bar chart displays the top 20 most populous countries from the United Nations World Population Prospects 2019 dataset as horizontal bars. The visualization shows population values with formatted tick labels (e.g., “1.4B”) and a Poppins font style. Built with React and D3 v5, it uses `scaleBand` and `scaleLinear` for axes, SVG `rect` elements for the marks, and native `<title>` tooltips. The chart intentionally omits traditional axes, relying instead on custom tick marks and labels for a clean, aesthetic presentation.
