🔧 Usage Instructions

Accessing Process Mining

  1. Load data (sample, upload, or ClickHouse)
  2. Configure and run funnel analysis
  3. Navigate to 🔍 Process Mining tab
  4. Configure analysis parameters
  5. Click 🚀 Discover Process
  6. Explore interactive diagram and data tables

Customization Options

# Example process mining call:
process_data = path_analyzer.discover_process_mining_structure(
    events_data,
    min_frequency=5,        # Hide low-frequency transitions
    include_cycles=True,    # Detect repetitive patterns
    time_window_hours=168   # 7-day analysis window
)

# Create visualization:
fig = visualizer.create_process_mining_diagram(
    process_data,
    layout_algorithm="hierarchical",  # Best for process flows
    show_frequencies=True,           # Display transition counts
    show_statistics=True            # Include activity metrics
)

🚀 Next Steps

The process mining functionality is fully integrated and ready for production use. The implementation provides:

  • ✅ Complete process discovery from user events
