This stylized bar chart displays the top 10 countries by population in 2020, using horizontal bars with teal fills that turn orange on hover. Built with React and D3’s `scaleBand` and `scaleLinear`, it loads CSV data via the `csv` function from `d3-fetch`, formats axis ticks with `format('.2s')`, and renders as SVG. The chart includes labeled axes and native tooltips via the `<title>` element.
