This interactive scatterplot displays the classic Iris flower dataset, plotting petal and sepal measurements against each other with points colored by species. Users can switch the X and Y axes via dropdown menus and hover over the color legend to highlight a particular species while fading the others. The visualization uses React with D3's `scaleLinear` and `scaleOrdinal` for axes and color encoding, rendered as SVG circles with hover-based opacity transitions on the legend items.
