This example visualizes the Iris Dataset as a scatter plot, mapping petal length and width to the x- and y-axes, with points colored by species (blue for setosa, red for versicolor, black for virginica). It uses D3 v6 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, scale coordinates, and render axes. Although the circles are drawn using `selectAll` and `join`, the code also sets non-standard `rx` and `ry` attributes from sepal measurements, though these do not affect the circular shape. The plot fills the entire window and is rendered as SVG.
