This scatter plot displays the Iris dataset, mapping petal length and width for each sample while using color to distinguish between the three species (setosa, versicolor, and virginica). It also encodes sepal dimensions as the `rx` and `ry` attributes, though the circles are rendered with a fixed radius, making these values not visually apparent. The visualization is built with D3 v6, loading the CSV data via `d3.csv`, and using `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to construct the scales and axes. SVG circles are drawn on a full-window canvas, with a red title and green axis labels.
