This example demonstrates the reusable scatter plot pattern from Mike Bostock’s “Towards Reusable Charts,” applied to the Iris Dataset. It animates a transition every three seconds, cycling through four measured flower attributes (petal width, sepal width, petal length, and sepal length) as the x-axis variable. Built with d3.v6, the chart uses `scaleLinear`, `axisLeft`, `axisBottom`, and `selection.join` to smoothly update circle positions with a 1000ms `transition`, while axes re-scale in tandem. SVG rendering fills the full browser viewport, with styling from the Share Tech font.
