This example shows a horizontal bar chart built with React and D3 v6, displaying the first three rows of a CSV dataset. The chart maps each data point’s `Origin` category to the y-axis band scale and its `Cylinders` value to the x-axis linear scale, rendering `<rect>` SVG elements. Data is loaded asynchronously via `d3.csv` into React state using the `useEffect` and `useState` hooks, with the final SVG output managed by ReactDOM. The visualization relies on `scaleBand`, `scaleLinear`, and `max` from D3.
