This interactive scatter plot displays the classic Iris dataset, letting users choose any two attributes for the x- and y-axes via React dropdown menus. The visualization uses an interactive color legend where hovering over a species name dims all other points, highlighting the selected species. Built with React and D3 v5, the chart uses `scaleLinear` and `scaleOrdinal` to map measurements and species to positions and colors, rendering all marks as SVG circles.
