This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal dimensions by selecting attributes from dropdown menus for the x- and y-axes. Built with React and D3 v5, it renders SVG marks with tooltips showing formatted values. The chart updates scales and axes in response to menu changes, demonstrating how to combine React state management with D3's `scaleLinear`, `extent`, and `csv` data loading.
