This interactive scatter plot visualizes the Iris dataset, letting users select which of five attributes (sepal length/width, petal length/width, or species) to map to the x- and y-axes via React-controlled dropdown menus. The SVG chart uses `d3.scaleLinear` for both axes and renders circles for each data point, with hover highlighting and a native `<title>` tooltip. Built with React hooks (`useState`, `useEffect`) and D3 v6 utilities (`csv`, `extent`, `max`, `format`), it updates scales on user selections.
