This example presents an animated, reusable D3 scatter plot template that cycles through different iris flower measurements every four seconds, transitioning the x-axis, labels, and circle positions. The visualization loads the classic Iris dataset from a GitHub gist via `d3.csv`, then uses D3 v7 scales, axes, and a custom `scatterPlot` function to render the responsive full-screen SVG. The code employs `transition` with a 3000-millisecond duration to smoothly move data points and slide in new x-axis labels, while the y-axis remains fixed on sepal length.
