A 3D scatter plot of the Iris dataset, rendered as colored sprites in a Three.js scene. The visualization maps petal length, petal width, and sepal width to x, y, and z axes, with species determining color via a d3.scaleOrdinal and schemeCategory10. The plot rotates automatically and supports pan-based rotation through d3.zoom. This variant uses an HiDPI canvas technique, rendering at double resolution with a scaleFactor of 2 and setting the canvas CSS size accordingly.
