This interactive scatterplot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements through dropdown menus that change the x and y axes. Hovering over a species in the color legend fades out points from other species, highlighting the selected category. Built with React and D3 v5, the SVG visualization uses d3.scaleLinear, d3.scaleOrdinal, and d3.csv for data loading, with custom React components for axes, marks, and interactive filtering.
