This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between four numeric measurements (sepal and petal length/width) while color-coding points by species. Two dropdown menus, built with `react-dropdown`, let viewers dynamically select which attributes appear on the x- and y-axes, with axis labels updating accordingly. The visualization uses `d3.scaleLinear` for positional encoding, `d3.scaleOrdinal` to assign categorical colors to the three Iris species, and React hooks (`useState`, `useEffect`) to manage data loading and UI state. SVG circles are rendered via custom React components, with tooltips showing formatted values.
