This example shows the classic Iris dataset as a slowly rotating 3D scatter plot, with each flower species colored distinctly. The code maps three measured attributes (petal length, width, and sepal width) to the x, y, and z axes, rendering points as soft, glowing sprites using Three.js and its WebGL renderer. D3 handles data loading and scaling, while a custom radial gradient creates the firefly-like visual effect. The plot auto-rotates and also responds to mouse panning to adjust the viewing angle, all on a black, high-DPI canvas.
