This interactive scatterplot visualizes the classic Iris flower dataset, letting users explore relationships between sepal and petal measurements across three species. Two dropdown menus dynamically change which attribute is plotted on the x and y axes, while a color legend distinguishes species and supports hover filtering to fade unrelated points. Built with React and D3 v5, the visualization uses `scaleLinear` for axes, `scaleOrdinal` for colors, and renders all marks as SVG circles with native tooltips.
