This interactive scatter plot visualizes the Iris Dataset from a gist, showing measurements of sepal length, width, petal length, and width for three iris species. Users select the x and y axes via React dropdowns, and hovering over the color legend highlights data points of a selected species while fading the others. The visualization uses d3.scaleLinear and d3.scaleOrdinal for scales, renders as SVG with React components, and implements the color legend with interactive hover events.
