This is a horizontal bar chart that displays the 2020 population estimates for 30 countries, sorted by country name. The bars are rendered as green SVG rectangles, with the x-axis representing population values in billions and the y-axis listing country names. Built with React and D3 v5, the chart uses `scaleBand` for the categorical y-axis, `scaleLinear` for the quantitative x-axis, and custom React components for the axes and marks. Population data is loaded from a CSV file via `d3.csv` and formatted using `d3.format`.
