This example showcases the classic Iris dataset as an animated scatter plot. It cycles through the four numeric columns (petal and sepal measurements) on the x-axis every two seconds, while the y-axis displays sepal length. The visualization uses D3.js v6, specifically leveraging `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` within a custom reusable `scatterPlot` function. It renders as an interactive SVG, with animated axes and circular marks that update as the data mapping changes.
