📊 XY Projection Graph — Horizontal Plane (X vs Z) • Observe pendulum motion paths
The trail shows the bob's projection on the horizontal plane. Closed curves = regular motion • Complex rosettes = spherical 3D dynamics. The wireframe sphere in 3D view is the constraint "field" (center = pivot X, radius = L).
