This interactive scatter plot visualizes the Iris dataset, showing relationships between four flower measurements (sepal length/width, petal length/width) across three species. Users select which attributes to plot on the x- and y-axes via ReactDropdown menus, with points colored by species. Hovering over the color legend highlights one species while fading the others. Built with React and D3 v5, it uses `scaleLinear`, `scaleOrdinal`, and SVG circles, with axes rendered as custom tick components.
