This interactive scatterplot displays the Iris flower dataset, allowing viewers to explore relationships between four measured attributes by swapping either axis via dropdown menus. The visualization uses React to manage state and render SVG elements, while D3 v5 handles data loading, scales, and axis generation. Colors and sizes remain constant for all points, with hover tooltips showing formatted x-axis values. The two menus independently control which attribute appears on each axis, enabling immediate comparison across all attribute pairs.
