This interactive scatter plot displays the Iris flower dataset, showing how sepal and petal measurements vary across three species. Users select which measurement appears on each axis from dropdown menus, while a color legend identifies species. The visualization uses React with D3 v5 utilities, including `scaleLinear`, `scaleOrdinal`, and `extent` to map data to SVG circles. Coordinates derive from the selected CSV-loaded measurements, with axes rendered by custom React components using D3 scales.
