This interactive scatter plot visualizes the classic Iris flower dataset, allowing users to explore relationships between sepal and petal measurements across three species. The visualization uses React for state management and d3.scaleLinear and d3.scaleOrdinal to map data to positions and colors. Two dropdown menus let users switch which measurements appear on the x and y axes, while hovering over the color legend or data points dims unrelated marks via opacity transitions. The SVG rendering includes custom axes and a metadata tooltip powered by SVG title elements.
