This example shows a horizontal bar chart of population figures for 30 countries in 2020, with a green bar for each country and a blue axis grid. The visualization uses React to render SVG elements, with D3 v5’s `scaleBand` and `scaleLinear` to map country names and population values to positions. The bar lengths encode the population data, which is loaded from a remote CSV via D3’s `csv` method, and a native SVG `<title>` element provides tooltips on hover. Axis labels are formatted using D3’s `format` helper to abbreviate large numbers.
