This scatter plot visualizes the Iris dataset, mapping petal length and width on the x- and y-axes, with each point colored by species (setosa, versicolor, virginica). The plot uses D3 v6.7.0’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs to construct the chart, which is rendered as an SVG. Data is loaded from a remote CSV using D3’s `csv` helper, and circles are positioned with attributes for `cx`, `cy`, and fill color, though the code also encodes non-visual sepal measurements in unused `rx` and `ry` properties.
