This example shows a horizontal bar chart comparing the populations of ten countries, represented as SVG rectangles encoded by length along the x-axis. The chart’s axes are composed from React components (AxisBottom, AxisLeft, Marks) that render D3 scales (scaleBand, scaleLinear) and ticks. Data is loaded asynchronously from a CSV using D3’s `csv` function and `useData` hook, while the y-axis labels use the band scale’s domain and bandwidth.
