This example presents a reusable scatter plot of the Iris dataset, encoding species with distinct colors and shapes while mapping petal width and sepal length to the x and y axes. It cycles through four quantitative columns every ten seconds, updating the x-axis domain and point positions with animation. The visualization uses the D3 v6 module API, including `scaleLinear`, `scaleOrdinal`, `axisBottom`, `axisLeft`, and `symbol` for shape encoding, with SVG rendering driven by a `setInterval` loop that re-invokes the chart function.
