This interactive scatterplot displays the Iris flower dataset, allowing the user to select which attributes are mapped to the x- and y-axes via two dropdown menus. A color legend on the right encodes the flower species, and hovering over a legend entry dims points from other species while highlighting the matching ones. Built with React and D3 v5, it uses `scaleLinear`, `scaleOrdinal`, and custom React components for axes and marks, rendering to SVG from parsed CSV data.
