This interactive scatterplot explores the classic Iris flower dataset, allowing users to compare any two measurements by selecting attributes from dropdown menus. Each point represents a flower specimen, colored by species using a d3.scaleOrdinal with a categorical color palette. The visualization is built with React and rendered as SVG, using d3.scaleLinear for axes and d3.extent to compute domains. Mouse hover reveals tooltips with formatted values, while axis labels update dynamically based on the selected attributes.
