This interactive scatter plot visualizes the Iris flower dataset, letting users explore relationships between four numeric attributes by selecting which ones appear on the x- and y-axes via React dropdown menus. Each point represents a flower, colored by species according to a d3.scaleOrdinal mapping. The visualization uses React components to render SVG elements, with d3.scaleLinear for axes and d3.extent for domains. The code loads data from a CSV file using d3.csv and renders custom axis components with tick marks.
