This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between measurements like petal length and sepal width. A color legend maps the three Iris species to distinct hues, and hovering over a legend item highlights only the corresponding species points while dimming others. Built with React and D3 v5, the chart uses D3 scales for axes and colors, with custom SVG marks for data points. Dropdown menus for selecting X and Y attributes are implemented using the react-dropdown library, and axes are rendered via separate components.
