This example shows a horizontal bar chart of population data for ten countries, with axes rendered as React components. The chart uses D3’s `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis, while the axis ticks and grid lines are generated by mapping over the scales inside JSX. Data comes from a CSV file parsed with D3’s `csv` function, and the bars are drawn as SVG `<rect>` elements. The code explicitly imports React and D3 utilities, demonstrating a hybrid approach where React manages the DOM and D3 provides scaling and data parsing.
