This interactive scatterplot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements through menus in D3 v7 with React. Circles representing flowers animate smoothly between positions using d3.transition when axis selections change, while colors denote species. The visualization implements a reusable scatterPlot function with d3.scaleLinear, d3.scaleOrdinal, and axis components, rendered as SVG elements.
