This visualization displays a scatter plot of the Iris dataset, plotting petal length against petal width, with points colored by species (setosa, versicolor, or virginica). The chart uses D3 v6’s `scaleLinear`, `axisLeft`, and `axisBottom` to render axes, while SVG circles are sized by sepal length and width via the `rx` and `ry` attributes, creating an ellipse-like marker. Data is loaded asynchronously from a remote CSV using `d3.csv`, and the plot fills the browser window with margins configured for axis labels.
