This animated scatter plot visualizes the Iris Dataset, allowing users to dynamically switch which quantitative measurements (sepal length/width, petal length/width) appear on the x- and y-axes via drop-down menus. Using D3.js selection joins, circles animate smoothly between positions when axes change, with staggered transitions for updates and radius-growing effects on entry. The chart renders as SVG with animated axes and a categorical species option included in the menu.
