This example shows a horizontal bar graph comparing the population of ten countries, using a dataset loaded from a GitHub gist. The graph renders as an SVG in React, with bars and axes created through React components. It uses D3’s `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, along with `max` to compute the scale domain. The `csv` function from D3 loads and parses the data, which is managed with React’s `useState` and `useEffect` hooks.
