Data Flow
Upload & Parse Flow
User → Frontend → API /upload → io.save_upload()
↓
io.load_graph_from_file()
↓
NetworkX graph loaded
↓
Stored in GRAPH_REGISTRY
↓
Return graph_id to frontend
Analysis Job Flow
User → Frontend → API /analysis/centrality
↓
Create Celery task
↓
Return job_id
↓
Task queued in Redis
↓
Worker picks up task
↓
task.update_state(progress=30)
↓
services.metrics.compute_centrality()
↓
Save results to /data/artifacts/
↓
task.update_state(progress=100, result={...})
↓
User ← Frontend ← API /jobs/{job_id} ← Redis result backend

Graph Registry (In-Memory)
GRAPH_REGISTRY = {
"<graph_id>": {
"graph": nx.Graph(), # NetworkX graph
"filepath": "/data/uploads/...", # Original file
"positions": [NodePosition()], # Layout positions
"metadata": {} # Extra info
}
}
Job State (Redis)
{
"job_id": "uuid",
"status": "running", # queued|running|completed|failed
"progress": 50, # 0-100
"phase": "computing", # human-readable
"result": {...} # Output data
}

Security Architecture
Current (Development Mode)
✓ Read-only py3plex mount
✓ Isolated data directories
✗ CORS allows all origins
✗ No authentication
✗ No HTTPS
✗ No rate limiting
Production Hardening
Note: The GUI is designed for local development and research use. For production deployment, consider the following security enhancements:
Security Checklist:
Security Feature |
Implementation Notes |
|---|---|
HTTPS/TLS |
Use nginx or Caddy as reverse proxy with SSL certificates |
Authentication |
Implement OAuth2 or JWT-based authentication |
Authorization |
Role-based access control (RBAC) for multi-user environments |
CORS Configuration |
Restrict allowed origins to specific domains |
Rate Limiting |
Use nginx rate limiting or FastAPI middleware |
Input Validation |
Sanitize all user inputs (file uploads, query strings) |
Data Isolation |
Separate user workspaces with filesystem permissions |
Audit Logging |
Log all API access and queries for security auditing |
Dependency Updates |
Regularly update frontend and backend dependencies |
Container Security |
Use minimal base images, scan for vulnerabilities |
Recommended Production Architecture:

Performance Characteristics
Small Graphs (< 100 nodes)
Upload: < 1s
Layout: 2-5s
Centrality: 1-3s
Community: 1-3s
Medium Graphs (100-1000 nodes)
Upload: 1-3s
Layout: 5-15s
Centrality: 3-10s
Community: 3-10s
Large Graphs (> 1000 nodes)
Consider sampling for preview
Progressive rendering recommended
May need GPU acceleration
Memory: ~1GB per 10k nodes
Future Enhancements
Phase 2

Database backend (PostgreSQL)
Authentication service
CI/CD pipeline
Phase 3
GraphQL API
Plugin system
Custom algorithms
