This animated scatter plot cycles through different combinations of Iris flower measurements, displaying sepal and petal dimensions on the x- and y-axes. The visualization uses D3 v6 to render circles colored by species (setosa, versicolor, virginica) with a custom legend, while a `setInterval` triggers updates to the axis scales and labels. Data comes from a CSV of the classic Iris dataset loaded via `d3.csv`. The code leverages reusable chart patterns from `scatterPlot.js` with `scaleLinear`, `axisLeft`, and `axisBottom` APIs, alongside a fixed y-axis label for sepal length.
