This interactive scatter plot visualizes the Iris dataset, showing the relationships between four flower measurements with points colored by species. Two dropdown menus allow users to select which features appear on the x and y axes. Hovering over a point highlights all points of the same species while fading others, and the interactive legend responds to hover events. The visualization uses d3.v7 with scaleLinear, extent, axisBottom, and axisLeft to render the SVG axes and circles, with animations triggered by menu changes.
