This interactive scatter plot displays the Iris flower dataset, letting users explore relationships between sepal and petal measurements through dropdown menus that control the x and y axes. The visualization, rendered with React and D3 v7, uses `scaleLinear` for axes, `scaleOrdinal` for species coloring, and SVG circles for data points. Hovering over the color legend highlights a selected species while dimming others, and tooltips reveal exact values via SVG `<title>` elements.
