This bar chart displays the 2020 population for 30 countries, sorted along a linear scale, with country names on the y-axis. Built with React and D3 v5, it creates an SVG using `scaleBand` for the categorical axis, `scaleLinear` for the numeric axis, and custom `AxisBottom`, `AxisLeft`, and `Marks` components. The data comes from a CSV file loaded with `d3.csv`.
