This stylized bar chart displays the populations of the top ten countries in 2020 using horizontal bars. The visualization uses React state to load and manage data from a UN Population CSV file, with D3 v5 utilities like `csv()`, `scaleBand()`, and `scaleLinear()` to map values. SVG rectangles render the bars, colored orange with a Poppins font, while axes include formatted tick labels using `format('.2s')`. Tooltips appear via SVG `<title>` elements, and the chart is fully responsive to its 960x500 frame.
