This visualization shows a scatter plot of the Iris dataset, using different colors to distinguish the three species (setosa, versicolor, and virginica). It maps petal measurements to the x and y axes while additionally encoding sepal measurements as the rx and ry attributes of each circle, creating a hybrid scatter plot. The code loads the CSV data via `d3.csv`, uses `scaleLinear` for axis scaling, and renders SVG circles with `selectAll` and `join`. Axis labels are added as text, with the petal axis rotated using `transform`.
