This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements. Dropdown menus control which attributes map to the x- and y-axes, with the SVG marks updating accordingly. The React component uses `useState` and `useCallback` to manage selections, while `d3.csv` loads the data and `d3.scaleLinear` with `extent` handles scaling. Axes are rendered as custom SVG components, and a native `<title>` element provides tooltips on each circle.
