This interactive scatter plot visualizes the Iris dataset, showing relationships between sepal and petal measurements across three flower species. Users can dynamically switch which measurements appear on the x and y axes using dropdown menus. The visualization uses D3 scales and axes for data mapping, while React manages the component state and UI controls. Points are rendered as colored circles in SVG, with a legend indicating species assignments. The code follows the React & D3 pattern where React handles the interface and D3’s selection methods update the SVG elements.
