This stylized bar chart displays the populations of ten countries using data from the UN Population 2019 dataset. The visualization uses React components to render SVG elements, with d3.scaleBand and d3.scaleLinear mapping countries and population values to screen coordinates. Custom AxisBottom and AxisLeft components generate tick marks and labels, while the Marks component renders rectangles with tooltips. The chart features a clean design with Poppins typography, a teal color scheme, and formatted population labels using d3.format.
