This stylized bar chart displays the populations of the top 10 countries from the UN Population 2019 dataset. It uses React with D3 v6’s `scaleBand` and `scaleLinear` to map countries and population values, rendering bars as SVG rectangles with tooltips via the `<title>` element. The chart includes formatted axis ticks using `d3.format` and a Poppins font, with axes built from custom React components.
