This animated scatter plot displays the Iris dataset, cycling through four different flower measurements every three seconds. Built with D3 v6, it uses a reusable chart module with `selection.join` to smoothly transition circles and axes between updates, animating position via `transition.delay` and growing new circles from radius zero. The visualization reads CSV data from a GitHub gist, renders as SVG, and leverages `scaleLinear`, `axisLeft`, and `axisBottom` to map the data.
