This scatter plot of the Iris dataset uses interactive dropdown menus to explore relationships between measurements. Users can select different attributes for the X and Y axes, and the visualization color-codes each point by species using a D3 ordinal scale. Built with React and rendered as SVG, it uses `scaleLinear` for axes, `scaleOrdinal` for colors, and custom React components for the dropdowns and marks. The plot includes axis labels and tick formatting via `format('.2s')`, with tooltips showing the x-value on hover.
