This interactive scatterplot displays the Iris flower dataset, letting users explore relationships between sepal and petal measurements through dropdown menus that change the x and y axes. Hovering over a species in the color legend highlights all matching data points while fading the others to 50% opacity. The visualization uses React for UI state management, d3.scaleLinear and d3.scaleOrdinal for scaling, and renders SVG circles with tooltips for exact values.
