This animated scatterplot visualizes the Iris flower dataset, with points colored and shaped by species and mapped to petal length, sepal length, and width scales. Built with D3 v6, it uses `scaleLinear`, `scaleOrdinal`, `symbol`, and `transition` to animate circle positions and radii. The reusable `scatterPlot` module updates marks via data joins, while axes redraw smoothly as the view transitions.
