This visualization presents a horizontal bar chart of population data for ten countries, using a green fill for each bar. The chart is rendered as an SVG within a React application, leveraging D3.v5 for data processing and scale construction. The code demonstrates modular components for axes and marks, employing D3's `scaleBand` and `scaleLinear` for positioning. Population values are loaded from a remote CSV file, formatted with D3's `format` function to display values like "1.2B". Tooltips are provided via SVG `<title>` elements, and the chart includes styled blue tick lines and labeled axes.
