This interactive scatter plot visualizes the Iris flower dataset, letting users explore the relationships between sepal and petal dimensions through dropdown menus. The visualization uses React, a D3 component architecture, and SVG rendering to display data points colored by species. Hovering over the interactive color legend highlights points from a particular species while fading the others, using React state management and mouse event handlers to dynamically adjust opacity. The plot features D3's linear scales for axes and an ordinal color scale for categorical species assignment.
