This visualization displays the classic Iris dataset as a scatter plot, mapping petal length and width on the x- and y-axes while encoding sepal dimensions through elliptical markers whose rx and ry attributes correspond to sepal length and width. Species are represented by distinct colors: purple for setosa, brown for versicolor, and pink for virginica. The code uses D3 v6’s `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and `csv` loader within a React-free SVG rendering approach. Axes labels indicate measurements, and the plot fills the browser window with a 24-pixel tick font.
