Graph Algorithms Visualizer

A desktop application built with Qt for visualizing graph algorithms, managing user accounts, and interacting with graph structures in real-time.

Features

Graph Operations

• Add/delete nodes (cities) and edges with weights
• Visualize graph traversal (DFS, BFS) with step-by-step color highlighting
• Compute shortest paths using Dijkstra's algorithm and Floyd-Warshall algorithm
• Display results in tables (Floyd-Warshall matrix) and path sequences
• Interactive node dragging with real-time edge updates

User Management

• Secure registration/login system with input validation
• Persistent JSON storage for:
  • User credentials
  • Graph states
  • Algorithm results
• Session management with logout/exit functionality

UI/UX

• Responsive full-screen mode (press ESC to exit)
• Clear error messages for invalid inputs (red-bordered fields)
• Color-coded node highlighting during algorithm execution
• Scrollable table view for large datasets (Floyd-Warshall)
• Clean input field reset after operations.
