This interactive scatterplot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements. The visualization uses D3 v7 with SVG rendering, featuring dropdown menus to select which columns map to the x and y axes. When users change selections, the scatterplot animates using D3 transitions, with circles smoothly repositioning and axes updating over a one-second duration. The implementation uses d3.scaleLinear for axis scaling, d3.extent for domain calculation, and a custom menu component with D3's dispatch system to handle user interactions.
