This interactive scatter plot explores the Iris dataset, allowing users to dynamically select which flower measurements appear on the x and y axes via React dropdown menus. Hovering over the color legend for species fades unrelated points and highlights the selected group. Built with React and D3 v6, the visualization uses `scaleLinear`, `scaleOrdinal`, `csv`, `extent`, and `format` to render SVG circles and axes, with brush-free interactivity driven by React state hooks.
