Algorithm Visualizer

An interactive PyQt6 application visualizing sorting, graph search, and pathfinding algorithms as generators.

Features

• Visualize sorting algorithms: Bubble Sort, Merge Sort, Quick Sort, Heap Sort
• Visualize graph algorithms: Breadth-First Search (BFS), Depth-First Search (DFS), Dijkstra's algorithm
• Visualize pathfinding algorithms: A* and BFS on a 2D grid with interactive wall drawing
• Adjustable animation speed and array size
• Step-by-step algorithm execution via generator-based implementations
• Dark theme with color-coded steps for clarity
• Built with PyQt6 for a responsive desktop interface

Getting started

Prerequisites: Python 3 (PyQt6 is installed from requirements.txt).

1. Clone the repository.
2. Install dependencies: pip install -r requirements.txt
3. Run the application: python main.py
