Nested scene graph: a simple solar system
This example shows how a scene graph composes rotation and translation: the root group rotates, child groups represent orbits, and circles represent celestial bodies. It is a compact illustration of parent–child transforms and per-frame updates from Lesson 3 — Scene graph and transform.
The demo runs inside <ic-canvas> and updates transforms on each frame, which is the same mental model as building more complex diagrams or games on an infinite canvas.
