This example presents a scatter plot of the Iris Dataset, showing the relationship between sepal and petal measurements across flower species. The visualization uses React hooks, specifically `useState` and `useEffect`, to load CSV data via d3.csv and transform numeric fields. The rendering relies on D3 v5 to create the scatter plot, with the dataset sourced from a GitHub gist. A separate message element displays static text, while the main chart visualizes the four iris features.
