Qt Graph Visualizer

This project is a simple interactive graph editor built with Qt (C++/QtWidgets). It allows users to add, remove, move, and connect nodes visually, and provides support for import/export of the graph structure using JSON files.

✨ Features

• Add / remove nodes
• Drag and move nodes
• Connect nodes with edges
• Edge arrows for direction
• Customizable node and edge colors
• Configurable node radius
• Import/Export graph to JSON

📋 Todo

• Add/Remove Nodes and Edges
• Visual edge arrow direction
• Import/Export JSON support
• Add edge weights
• Add labels to nodes and edges
• Highlight selected edges
• Save and load node colors/radius
• Implement pathfinding algorithms:
  • Dijkstra's Algorithm (shortest path)
  • A* Search Algorithm
• Implement Minimum Spanning Tree (MST):
  • Prim's Algorithm
  • Kruskal's Algorithm
• Visual animation for algorithm steps
• Undo/Redo support
• Search node by ID or label
• Save as image (SVG, PNG)
