This interactive scatter plot visualizes the Iris dataset, with each point colored by species (setosa, versicolor, or virginica). The visualization cycles through four different x-axis attributes—petal width, sepal width, petal length, and sepal length—at regular intervals, updating the chart dynamically using `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`. A legend and axis labels are rendered as SVG text elements. The animation is driven by `setInterval`, which re-calls the reusable `scatterPlot` function built on D3 v6.
