🤝 Friend Recommendation using Graph Neural Network (GNN)

A simple Graph Neural Network (GNN) project that recommends new friendships in a small social network.
Built using PyTorch Geometric in Google Colab or Locally (Python 3.9+).

🌟 Project Idea

• Each person = Node
• Each friendship = Edge
• GNN learns embeddings for people
• Link prediction suggests possible new friendships
