This interactive scatterplot visualizes the Iris flower dataset, plotting sepal and petal measurements against each other. Users can switch the X and Y axes via dropdown menus, while a color legend distinguishes the three iris species. Hovering over a legend item fades non-matching points and highlights the selected species. The visualization uses React with D3.js scales (scaleLinear, scaleOrdinal) for positioning and coloring, the react-dropdown library for axis selection, and renders SVG circles with tooltips.
