GraphVisualizer

The main 3D renderer using React Three Fiber and custom shader effects. It renders nodes, links, community boundaries, and background atmosphere.

Features

• Force-directed 3D layout with spherical knowledge-universe constraint
• Node size encodes centrality; link thickness encodes weight
• Search highlighting (debounced) without re-running layout
• “Community Isolator” fades non-hierarchy nodes/links
• Post-processing: bloom, vignette, nebula background

Props (selected)

• layout: processed nodes, links, communities (from ForceSimulation3D)
• selectedEntityTypes: filter set
• minRelationshipWeight: link cutoff
• communityMode: ‘off’ | ‘auto’ | ‘all’
• visibleCommunities: precomputed hierarchy to show
• selectedNode, onNodeSelect for inspection

Performance Notes

• Shared shader material cloned per node for independent uniforms
• Precomputed node size/color and community bounds/hierarchy
• Debounced search string to limit rerenders
