This example presents a horizontal bar chart of United Nations population data for ten countries, rendered as an SVG. The React app uses a D3 CSV utility to fetch and parse the data, then employs D3’s `scaleBand` and `scaleLinear` to map countries and population values to coordinates. Axis ticks and labels are generated manually via `scale.ticks()`, while D3’s `max` function defines the scale domain. The React component manages state with hooks, rendering all bars and text directly in JSX.
