🏗️ Architecture

This application uses a modular structure for scalability and clarity. Below is a class diagram of key components.

Core Components

1. GUI (src/ui/GUI.cpp)

   • Main application controller
   • Handles window management
   • Coordinates user input

2. DrawingState (src/core/DrawingState.cpp)

   • Manages drawing state
   • Stores shapes and points
   • Handles color management

3. MenuBar (src/ui/components/MenuBar.cpp)

   • Handles menu interactions
   • Manages algorithm selection
   • Controls file operations

4. FileManager (src/utils/FileManager.cpp)

   • Handles saving/loading drawings
   • Manages file serialization
