This example demonstrates a dynamic scatter plot visualization of the Iris dataset, where the x-axis mapping cycles through four different flower measurements (petal width, sepal width, petal length, and sepal length) every three seconds. The plot uses D3's `scaleLinear`, `extent`, and axis components to render circles in SVG, updating the view via a custom reusable `scatterPlot` function with a join operator. Data is loaded from a CSV file using D3's `csv` parser.
