This stylized bar chart ranks ten countries by their 2020 population estimates from the UN Population dataset, with horizontal bars positioned by a d3.scaleBand and sized by a d3.scaleLinear. Each bar includes a native SVG `<title>` tooltip showing the formatted value, and the y-axis lists country names while the x-axis applies a custom tick formatter that converts units from "G" to "B". The visualization is built with React, rendered as SVG, and styled with the Poppins font for a clean, modern look.
