🚨 DDoS Stress Test Simulator

Added comprehensive network attack simulation system

• 5 Attack Patterns Implemented:

  • Flood Attack: High volume request spam
  • Slowloris: Slow connection exhaustion
  • SYN Flood: TCP handshake overflow
  • UDP Flood: UDP packet bombardment
  • HTTP Flood: Application layer saturation

• Metrics Dashboard:

  • Total requests tracking (successful/failed)
  • Read/write operations counters
  • Real-time throughput monitoring
  • Average response time calculation
  • Peak throughput tracking
  • Elapsed time display

• Visualization Features:

  • Custom throughput graph with gradient fill
  • Real-time data plotting with time-based X-axis
  • Attack intensity controls (0-100%)
  • Max requests per second configuration
  • Start/Stop attack controls

• Logging System:

  • Color-coded log levels (Info: blue, Warning: yellow, Error: red, Critical: bright red)
  • Timestamped entries
  • 1000-entry circular buffer
  • Separate Logs tab for detailed review
  • Optional log preservation across navigations

🧠 Neural Network Simulator

Added interactive neural network visualization with live signal propagation

• Configurable Architecture:

  • Input layers: 1-3 layers
  • Hidden layers: 1-5 layers
  • Output layers: 1-3 layers
  • Neurons per layer: customizable for each layer type

• Visualization:

  • Real-time neuron firing with color changes
  • Signal propagation through weighted synapses
  • Activation levels shown as inner circles
  • Automatic NN-style layout (horizontal layers)
  • Layer-based organization with proper spacing
  • Neuron activation value display (toggleable, shows 0.00-1.00 format in node centers)

• Customization:

  • Neuron colors (inactive, firing, input, output)
  • Synapse colors (inactive, active)
  • Fire rate: 0.1-10 Hz
  • Propagation speed: 0.1-2.0x
  • Show/hide neuron values option

• Statistics:

  • Real-time firing neuron count
  • Total neuron count
  • Network architecture summary

🎯 Navigation & UX Improvements

Enhanced graph navigation and user experience

• Initial Graph Centering:

  • Graph automatically centered when application loads
  • Improved first-time user experience
  • Proper viewport fitting on startup

💾 Import/Export System

Added comprehensive file operations

• Export Formats:

  • JSON: Complete graph structure with metadata
  • CSV: Node and edge listings with properties
  • Graphviz DOT: For external visualization tools

• Browser Integration:

  • File download via Blob API
  • Automatic filename generation
  • Proper MIME types for each format
  • Clean export dialog with format selection

• Import Support:

  • JSON graph import from local files
  • File upload trigger via browser file picker
  • Graceful error handling

🐛 Bug Fixes & Code Quality

Fixed compilation warnings and runtime issues

• Added #[allow(dead_code)] attributes for:

  • Unused NeuronState fields (layer, position, fire_time)
  • Unused loaded_file_name field
  • Unused ExportFormat::name() method

• Graph Visibility Fix:

  • Enabled fit_to_screen_enabled = true in initialization
  • Ensures graph is visible on first load
  • Prevents blank screen on startup

• Code Cleanup:

  • Removed dead code warnings
  • Proper error handling for browser APIs
  • Type safety improvements
