This stylized bar chart displays the population of ten countries from the UN Population 2019 dataset. Using React with D3 v7, the visualization employs `d3.scaleBand` and `d3.scaleLinear` to map data to SVG rectangles, with axes generated from `xScale.ticks()` and formatted using the SI format `.2s`. The chart features custom tick styling, axis labels, and tooltips via SVG `<title>` elements.
