This interactive scatter plot explores the Iris flower dataset, allowing users to dynamically select which measurements appear on the x- and y-axes through dropdown menus. The visualization is built using D3 v6's modular approach, combining a reusable `scatterPlot` function with a custom `menu` component that uses `d3.dispatch` for event handling. As users change axis selections, the plotted points and axis scales transition smoothly over a one-second duration using D3's `transition` API. The SVG rendering also includes a species-based categorical axis option, demonstrating both linear and point scales.
