This stylized bar chart displays the ten most populous countries using a clean, horizontal bar layout with a custom Poppins font and teal-colored bars. It reads population data from the United Nations World Population Prospects 2019 dataset via d3.csv, then uses d3.scaleBand and d3.scaleLinear to position bars and axes. The visualization is built as a React component, rendering SVG elements through React, with custom axis components and tooltips provided by SVG `<title>` elements. The x-axis uses `d3.format` to abbreviate large population values in billions.
