This visualization displays the Iris dataset as a scatter plot, using petal length and petal width to position circles colored by iris species (setosa, versicolor, and virginica). The SVG rendering uses D3 v6 APIs including `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and data joins via `selectAll` and `join`. Data is loaded asynchronously from a GitHub-hosted CSV using `d3.csv`, and each mark’s size and shape derive from sepal measurements, though the fixed radius and rx/ry attributes do not alter appearance. Axis labels are added as SVG text elements.
