Force Simulation

lib/forceSimulation.ts builds a 3D layout from GraphData using d3-force-3d with several customizations.

Highlights

• Community clustering force with cached centers on spherical shells
• Spherical constraint to maintain a coherent knowledge “universe”
• Node charge scaled by degree; link distance and strength from weight
• Precomputed node size/color and community bounds/hierarchy for render speed

Configuration (defaults)

• chargeStrength: -100
• linkDistance: 30
• linkStrength: 0.2
• collisionRadius: 6
• communityStrength: 0.2
• centerStrength: 0.02
