This example displays a horizontal bar chart comparing the populations of five countries, drawn as green SVG rectangles. The visualization uses D3 v6’s `scaleBand`, `scaleLinear`, and `axisBottom`/`axisLeft` to position bars and ticks, with data loaded from a local CSV file via `d3.csv`. The chart is entirely rendered through SVG elements within a React-agnostic HTML page, styled with CSS for body text and tick labels.
