This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between different flower measurements. The visualization uses D3 v6 to render animated SVG circles that transition smoothly when the X or Y axis is changed via dropdown menus. The code implements reusable modules for the scatter plot and menu components, using D3's `transition()` for animations, `scaleLinear()` for axis scaling, and the `csv()` function to load the dataset from a GitHub Gist.
