This interactive scatterplot lets users explore the classic Iris flower dataset by switching between four numeric measurements for the x- and y-axes via dropdown menus. The visualization uses React to manage state and render SVG circles, with D3 v5 providing scales, axes, and CSV data loading. Points are color-coded by iris species, and a legend identifies the three classes. The interface includes axis labels and tick marks generated with D3’s scale API, while React’s `useState` and `useEffect` handle data fetching and attribute selection.
