This interactive scatter plot visualizes the Iris Dataset, displaying measurements across quantitative axes selected via dropdown menus. The visualization implements a reusable chart pattern with `scatterPlot` and `menu` modules, using D3 v6's `selection.join` for smooth circle transitions and axis updates. Users can switch between petal width, sepal width, petal length, and species for either axis, triggering animated updates through `d3.transition`. Species data appears as categorical values, though the code currently maps multiple options to the same species column.
