This example displays the top 10 most populous countries as a horizontal bar chart using SVG. The chart is rendered with React and D3 v5, featuring axes created by the `AxisBottom` and `AxisLeft` components, which use `xScale.ticks()` and `yScale.domain()` respectively. The bars are drawn by the `Marks` component, which maps data to `rect` elements using `scaleBand` and `scaleLinear`. Data is loaded asynchronously from a UN World Population Prospects 2019 CSV file using D3’s `csv` function.
