This interactive scatter plot visualizes the Iris dataset, cycling through four feature combinations (petal width, sepal width, petal length, sepal length) on the x-axis every few seconds via `setInterval`. The y-axis shows sepal length, and each species—setosa, versicolor, and virginica—is color-coded using a `d3` scale and a custom marker function. Built with D3 v6, it uses `csv`, `scaleLinear`, `axisLeft`, and `axisBottom` to render SVG circles and axes, with a legend and axis labels updated dynamically.
