This interactive 3D scatterplot visualizes the Iris dataset, mapping sepal length, petal width, and petal length along three axes with points colored by species. The visualization renders as an SVG scene using D3 v4 with the d3-3d plugin, which projects 3D data onto a 2D plane, and includes a rotatable grid and y-axis scale. Users can drag to rotate the plot, with the rotation handled via D3's drag behavior and the d3-3d rotation methods, while points are drawn as circles updated through D3 transitions. The underlying data is loaded from a CSV file containing 150 iris flower measurements.
