Stylized Bar Chart
A stylized bar chart displays the top 10 most populous countries using data from the United Nations World Population Prospects 2019. The visualization renders horizontal bars as SVG rectangles via React components, with d3.scaleBand and d3.scaleLinear mapping country names to population values. D3’s format helper converts large numbers into abbreviated labels (e.g., “1.4B”), while custom axis components generate tick marks and gridlines. The chart uses a Poppins font and teal color scheme, with hover tooltips showing precise population figures.
