This scatter plot visualizes the Iris dataset, mapping petal length on the x-axis and petal width on the y-axis, with each point colored by species (skyblue for setosa, lightgreen for versicolor, orange for virginica). Built with d3.csv, d3.scaleLinear, d3.axisLeft, and d3.axisBottom, the SVG rendering uses circles positioned via data joins. Although the code defines sepal dimensions as rx and ry attributes, it ultimately applies a fixed radius of 5 pixels, so sepal values do not affect the visual output.
