This example presents an animated scatter plot of the classic Iris Dataset, cycling through different combinations of flower measurements every three seconds. The visualization leverages a reusable D3 chart factory to manage its own scales, axes, and circle marks. It employs D3's `selection.join` to smoothly transition entering, updating, and exiting circles, using `d3.transition` for easing position changes and staggered delays. Axis updates are also animated via transitions. The code imports specific utilities like `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` from D3 v6.
