This example presents the Iris Dataset as an animated scatter plot, visualizing relationships between sepal and petal measurements across three flower species. Users can dynamically switch the X and Y axes via dropdown menus, triggering smooth transitions of data points and axis labels. The visualization uses D3.js (version 6.7.0) with a reusable chart module, SVG rendering, and a 1000-millisecond transition duration to animate positional changes. The species are encoded through distinct symbol types from D3's symbol scale, while the menu system leverages D3's dispatch API for event handling.
