This example shows an interactive scatter plot of the Iris dataset, cycling through four different x-axis variables (petal width, sepal width, petal length, sepal length) on a timer using `setInterval`. The plot uses D3 v6’s `scaleLinear`, `axisLeft`, `axisBottom`, and `csv` loader, with circles colored by species (setosa, versicolor, virginica) via an inline switch. SVG circles are drawn with static positions, while a reusable `scatterPlot()` module updates axes and point placement, rendering in a React-free HTML page with custom CSS styling.
