This stylized bar chart displays the top 10 countries by population using D3.js v7 within a React application, rendered as SVG. The horizontal bars are colored teal with a Poppins font, and the chart includes labeled axes with formatted tick values that convert large numbers to abbreviated units (e.g., "B" for billions). The data comes from a UN Population 2019 CSV file, loaded with d3.csv. The visualization uses scaleBand for the y-axis, scaleLinear for the x-axis, and native SVG elements with React components for the axes and marks.
