This interactive scatterplot visualizes the Iris dataset, allowing users to explore relationships between four flower measurements. The chart uses dropdown menus to change which attributes appear on the x and y axes, with each of the three iris species represented by a distinct color. Built with React, the visualization uses D3 v7 scales for positioning and color encoding, rendering SVG circles with native `<title>` tooltips. The code leverages scaleLinear, scaleOrdinal, extent, and callback-driven state management.
