1. Content Extraction

# Extract data from GNN content
extractor = VisualizationDataExtractor()
data = extractor.extract_from_content(gnn_content)

2. Statistical Analysis

# Generate comprehensive statistics
stats = extractor.get_model_statistics(data)

3. Visualization Generation

# Create visualizations
visualizer = AdvancedVisualizer()

# Generate complete dashboard
dashboard = DashboardGenerator()
dashboard_path = dashboard.generate_dashboard(content, model_name, output_dir)

Error Handling and Recovery

Recovery Mechanisms

  • Dependency Failures: Graceful degradation to basic HTML
  • Data Extraction Errors: Error pages with diagnostic information
  • Visualization Failures: Alternative visualization methods
  • Export Failures: Multiple export format attempts

Error Reporting

# Comprehensive error reporting
if not success:
    error_page = generator._generate_error_page(model_name, errors)
    # Save error page for debugging

Performance Optimization

Caching Strategies

  • Data Extraction: Cache extracted data to avoid reprocessing
  • Visualization Generation: Cache generated visualizations
  • Dashboard Assembly: Incremental dashboard updates

Memory Management

  • Large Models: Streaming data processing for large models
  • Resource Cleanup: Automatic cleanup of temporary files
  • Memory Monitoring: Track memory usage during processing
