A scatter plot of the Iris dataset shows petal length against petal width, with each point colored by species (setosa, versicolor, and virginica). The visualization uses D3 v6, loading data from a CSV via `d3.csv`, and maps the x and y axes using `scaleLinear`. Circles are drawn with SVG `<circle>` elements, where the `rx` and `ry` attributes are set from sepal measurements, though the visual remains a standard circle. Axis labels are added manually with SVG text, and axes are rendered using `axisLeft` and `axisBottom` onto the SVG canvas.
