This bar chart displays the top 10 most populous countries using data from the United Nations World Population Prospects 2019. The chart features horizontal bars ordered by country, with a clean, styled aesthetic using the Poppins font and a teal color scheme. Axes are customized with D3's `scaleLinear` and `scaleBand` for positioned ticks, and tooltips using SVG `<title>` elements. Built with React and D3 v5, the visualization highlights the power of reusable components for crafting polished, readable charts.
