This example shows an animated scatter plot of the Iris dataset that cycles through four attribute pairs every three seconds. The code uses D3 v7 with `scaleLinear`, `axisLeft`, `axisBottom`, and `transition` to smoothly animate circle positions and axis updates. The reusable chart pattern exports a configurable `scatterPlot` function, with data loaded via `d3.csv` and rendered as SVG circles with a 1000ms transition.
