This fork of a stylized bar chart displays the top 10 most populous countries. Built with React and D3 v5, the visualization uses `scaleBand` for the x-axis and `scaleLinear` for the y-axis, with SVG rectangles for bars. The data comes from the United Nations World Population Prospects 2019. The code includes commented-out attempts at rotating axis labels and adjusting bar heights, reflecting an iterative development process. The y-axis uses a custom tick format converting G to B for billions.
