This example animates the classic Iris flower dataset, cycling through different measurement pairings on the x-axis while keeping sepal length as the y-axis. The scatter plot updates every few seconds, with each species (setosa, versicolor, virginica) represented by a distinct color. Built with D3.js v6, it uses the `csv` method to load data, appends SVG `circle` elements for marks, and relies on `setInterval()` to trigger the dynamic axis transitions. The visualization also includes a manually constructed legend and axis labels.
