This interactive scatter plot animates the Iris dataset, letting users explore relationships between sepal and petal measurements while filtering by species. Three dropdown menus control the x-axis, y-axis, and species stratification, triggering smooth transitions as points reposition. Built with D3 v6 and SVG, the visualization uses selection.join for enter-update-exit cycles, with circles growing from radius zero on entry. The code loads data via d3.csv and employs reusable chart and menu factory functions to manage state and dynamic updates.
