This example displays a horizontal bar chart of population data for 30 countries in 2020, sourced from a CSV file hosted on GitHub. It sorts countries along the y-axis using a band scale, while the x-axis uses a linear scale with SI-prefix formatting to abbreviate large numbers. Built with React and rendered as SVG, the chart creates bars using `rect` elements and provides tooltips via a `title` element. D3 functions like `scaleBand`, `scaleLinear`, and `format` handle the scaling and tick formatting.
