This interactive scatter plot visualizes the Iris flower dataset, displaying sepal and petal measurements for setosa, versicolor, and virginica species. Users can select which attributes appear on the x- and y-axes via React dropdown menus, while hovering over the color legend highlights only matching species points with d3 scaleOrdinal color mapping. The visualization uses React hooks for state management, d3.csv for data loading, and d3.scaleLinear for axis scaling, with SVG rendering for all marks and axes.
