This stylized bar chart displays population data for ten countries, with country names on the y-axis and population values on the x-axis, formatted in billions. Built with React and D3 v6, it uses `scaleBand` and `scaleLinear` for the axes and SVG `<rect>` elements for the bars, each with a native tooltip. The data is loaded from a Google Sheet via `d3.csv`. The chart features a clean, minimal design using the Poppins font and a teal color scheme.
