This interactive scatter plot visualizes the Iris dataset, mapping petal length against sepal width. A React component renders SVG circles colored by species using d3.scaleOrdinal, while d3.scaleLinear handles x and y positioning. Hovering over the color legend highlights points of that species and fades all others to 20% opacity. Axes are built with custom React tick components, and data loads asynchronously via d3.csv.
