This interactive scatter plot visualizes the Iris dataset, allowing users to dynamically change which attributes are mapped to the X and Y axes via HTML dropdown menus. The plot animates transitions between states, smoothly moving circles and updating axis labels when the selected variables change. Built with D3 v6, the example demonstrates a reusable chart architecture using custom components like `scatterPlot` and `menu`, leveraging D3's `dispatch` for event handling and `transition` for smooth animations.
