This stylized bar chart displays the top 10 most populous countries using data from the United Nations World Population Prospects 2019. The bars extend horizontally from the left axis, with country names as categorical labels and population values shown on a linear scale formatted with SI prefixes. The visualization uses React components with D3’s `scaleBand` and `scaleLinear` to position marks and axes, rendered as SVG rectangles with native tooltips. Styling includes the Poppins font and teal-colored bars, with a clean minimalist aesthetic.
