facett-graph3d — crate card

Reverse-engineered (from source — verify, don't trust the name)

• One-line pitch: A 3D graph viewer — the 3D-callgraph idea made generic: supply (label, color) nodes + edges, pick a layout, get a rotating depth-shaded node cloud.
• Does: Graph3D renders (label,color) nodes + edges with a Layout3D (sphere/helix), Y-axis spin, and depth cues (depth → size/brightness) via CPU orthographic projection. CallGraphLayout/louvain (community layouts), neon decor, and RabbitLogo3D (a lit extruded-rabbit logo). DecorPolicy (Off/FromTheme/Reduced/Full) drives how much neon beauty is painted, resolving from the active theme's EffectsPolicy. Feature wgpu adds a GPU depth-tested extruded-logo renderer (logo3d/gpu) and an instanced emissive node/edge lane with bloom (graph_gpu), folded onto facett-core's shared L0 offscreen colour+depth helper; CPU painter is the default/snapshot golden path.
• Key deps: facett-core (Facet, look/EffectsPolicy, render/decor, theme; shared L0 GPU via facett-core/wgpu), egui, serde_json; optional egui-wgpu/wgpu/bytemuck/pollster (GPU lane).
• Shape: lib; medium (callgraph_layouts/graph_gpu/logo3d(+gpu)/neon).
• Observed role in the workspace: Re-exported by umbrella facett as facett::graph3d; the umbrella graph3d-wgpu feature turns on its GPU lane. Generalises nornir's callgraph.rs.

• Why it exists (vs the obvious alternative):
• Hard constraint (airgap / no-C-deps / no-FFI / pure-Rust / etc.):
• Release cadence & independence (rides a parent? own repo someday?):
• Status (production / prototype / experimental / stubbed):
• Must-NOT-change invariant:
• Biggest known gap or TODO:
• Anything a newcomer would get wrong about it:
