This interactive scatter plot of the classic Iris dataset lets users explore relationships between sepal and petal measurements. Built with React and D3.js (v5), it renders 150 points as SVGs, colored by iris species. Users can select any measurement combination for the X and Y axes via dropdown menus. Hovering over a species in the color legend highlights that group's points while dimming others, using D3's scaleOrdinal for color mapping and scaleLinear for axes.
