This horizontal bar chart displays population figures for ten countries using the UN Population 2019 dataset. The visualization employs React with D3 v7, using `scaleBand` and `scaleLinear` to position bars and axes. Styled with the Prompt font and light blue semi-transparent bars, the chart includes red axis ticks and hover tooltips via SVG `<title>` elements. The bottom axis formats tick values with `d3.format` to display billions.
