This horizontal bar chart displays the populations of 30 countries in 2020, sorted by country name along the y-axis and population size along the x-axis. Built with React and D3 v5, it uses `scaleBand` for the categorical axis, `scaleLinear` for the numeric scale, and SVG `rect` elements for bars. Data loads from a CSV via the `csv` function, with population values converted from thousands, and axes are rendered by custom React components.
