This scatter plot visualizes the Iris dataset, plotting petal length on the x-axis and petal width on the y-axis, with data points colored by species (setosa, versicolor, virginica). The visualization is rendered as an SVG using D3 v6, employing `scaleLinear` for axes, `extent` for domain scaling, and `axisLeft`/`axisBottom` for ticks. Circle radii are fixed, while the code also maps sepal dimensions to `rx`/`ry` attributes, though these do not affect the circular marks. The plot includes rotated axis labels for petal length and sepal length.
