This animated scatter plot cycles through different Iris flower measurements, showing how the petal width, sepal width, petal length, and sepal length correlate across three species. The visualization updates at regular intervals via `setInterval`, using D3's `scaleLinear`, `axisLeft`, and `axisBottom` to render axes and circles. Data comes from a CSV file of the classic Iris dataset, with colors distinguishing species. Text labels and legends are added using D3 selections, and the layout adapts to the full browser window size.
