This visualization is an interactive scatter plot of the Iris dataset, displaying petal length and petal width for three flower species—setosa, versicolor, and virginica—distinguished by color. The plot uses D3 v6 APIs, including `csv` for data loading, `scaleLinear` for axes, and `axisLeft`/`axisBottom` for rendering the scales. It renders circles as SVG marks, with additional sepal measurements stored as properties but not used in the visual encoding. The chart is sized to the full window, with green axis labels and a red title.
