Stylized Bar Chart
This stylized bar chart displays the ten most populous countries using data from the United Nations World Population Prospects 2019. The visualization uses d3.scaleBand and d3.scaleLinear to map country names and population values to SVG rectangles, with axis components rendered as React components. The chart includes a formatted population axis using d3.format with a "G" to "B" replacement, and native SVG tooltips show exact values on hover.
