This D3.js scatter plot visualizes the Iris dataset, showing different flower measurements as points across a continuous animation. The chart cycles through four attribute combinations—petal width, sepal width, petal length, and sepal length—every two seconds, smoothly re-rendering axes and circles via the `scatterPlot` reusable chart API. It uses d3's `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and SVG `join` operations for declarative updates, while styling text with the Share Tech font.
