About Graph Modeling

Graphs are one of the most powerful data structures in computer science. They model relationships in social networks (Facebook, LinkedIn), navigation systems (Google Maps), recommendation engines (Netflix, Amazon), web search (Google PageRank), project planning (dependency graphs), and much more. By understanding graphs, you can solve complex real-world problems involving connections, paths, networks, and relationships. Every time you use GPS, browse social media, or get recommendations, you're interacting with graph algorithms!
