This scatter plot visualizes the Iris dataset, mapping petal length and width on the x- and y-axes, with circles colored by species (red, yellow, blue). It uses D3 v6’s `csv`, `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and SVG `circle` elements. Data loads from a remote CSV, and additional sepal dimensions are stored as circle properties but not visualized. Axes labels are added via SVG text, with a fixed radius of 5 pixels per point.
