3D Electrical Vector View

VCG → Lead projection (dot product)
Educational visualization: each ECG lead is a different projection of the same underlying cardiac electrical vector onto a lead axis. In this simulator, the instantaneous sample is computed as ECGlead(t) = VCG(t) · LeadAxis. The focused lead axis (green) updates when a lead strip is selected.

Legend: White triangle = VCG vector (and axes). Yellow triangle = VCG projection onto the focused lead axis (dot product → ECG sample).
Projection history (focused lead)
The sparkline shows recent dot-product samples for the focused lead (the same value that feeds its sweep strip).
