This example shows a horizontal bar chart ranking the populations of the world’s ten largest countries, sourced from a CSV file of 2020 estimates. It uses React to render SVG elements, while D3’s `scaleBand` and `scaleLinear` compute the layout and `csv` loads the data. The `AxisBottom` and `AxisLeft` components generate ticks and labels, and `Marks` draws each rectangle with a tooltip showing the country name.
