This stylized bar chart displays the top 10 countries by population for 2020, using a horizontal layout with rounded padding between bars. The visualization is built with React and D3 v5, employing D3's `csv`, `scaleBand`, `scaleLinear`, and `format` utilities to load and scale the data. SVG rectangles rendered via React component marks show the population values, with tooltips formatted using D3's SI notation (e.g., “1.43B”). The chart features a custom Poppins font and muted color palette applied through CSS.
