This interactive scatter plot displays the Iris dataset, using drop-down menus to select which measurements appear on each axis and color-coding points by species. An interactive color legend highlights points of a selected species while dimming others on mouse hover. Built with React and D3 v5, the visualization uses `scaleLinear`, `scaleOrdinal`, and SVG rendering with radial gradients for point fills. The legend and dropdowns respond to hover and change events, providing a focused exploration of species distributions across four flower attributes.
