This interactive scatterplot visualizes the Iris flower dataset, comparing sepal and petal measurements across three species. Users can dynamically select which attributes to plot on the X and Y axes via dropdown menus, with points colored by species using a d3.scaleOrdinal legend. Built with React and D3 v6, the SVG visualization renders axes and circular marks through reusable components, while d3.csv loads the data and d3.extent computes scale domains for responsive axis ranges.
