This scatter plot visualizes the Iris dataset, mapping petal length on the x-axis and petal width on the y-axis, with each point colored by species (setosa, versicolor, or virginica). The visualization uses D3 v7 with the `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and `csv` APIs to load and render the data as SVG circles. Axis labels indicate "Petal Length" and "Sepal Length," though the latter appears mislabeled relative to the plotted variables. The chart fills the browser window with margins and styled tick text.
