This example demonstrates a reusable scatter plot that visualizes the Iris Dataset, displaying measurements like petal width and sepal length as colored circles. It cycles through different column pairs every two seconds, animating the axes and points to show relationships between various flower attributes. The chart uses D3 v6 APIs including `scaleLinear`, `axisLeft`, `axisBottom`, and a custom `scatterPlot` function that follows the reusable chart pattern. Data loads via `csv` from a GitHub Gist, and the SVG rendering updates smoothly as the selected variables change.
