This interactive scatter plot visualizes the classic Iris dataset, displaying four measured flower attributes as colored points representing species. Users select which attributes to plot on the X and Y axes through React dropdown menus, with point colors determined by species using d3.scaleOrdinal. The visualization uses React hooks for state management and d3's scaling, axis, and CSV parsing functions (d3.csv, d3.scaleLinear, d3.extent, d3.format) to render marks as SVG circles.
