This interactive scatter plot visualizes the Iris dataset, using the D3.js version 5 library within a React framework to render SVG elements. Users can select which attributes to display on the X and Y axes via dropdown menus, with the initial setup showing species data colored by unique categories. The visualization includes an interactive color legend that allows users to hover over categorical labels to highlight specific data points while fading the others, implemented through custom React components that manage hover state and opacity transitions.
