This interactive scatter plot visualizes the Iris dataset, showing relationships between four flower measurements with points colored by species. Users can switch the X and Y axes via dropdown menus powered by ReactDropdown. Built with React and D3 v5, the visualization uses d3.scaleLinear for axes, d3.scaleOrdinal for species colors, and scales computed with d3.extent and d3.nice. SVG circles include tooltip titles, while axis components render ticks and labels.
