> [!tldr] A [[Graph]] representation using a list or a symmetric table. You can represent a graph using an **adjacency list** (or table) or an **adjacency matrix**. **Graph:** ![[Pasted image 20260605171322.png|406]] Equivalent **Adjacency List:** ![[Pasted image 20260605171435.png|292]] Equivalent **Adjacency Matrix:** ![[Pasted image 20260605171508.png|290]] For the adjacency matrix you have a natural place to place graph **weights**, or even hyperlinks if you were building out a clickable interface. I've seen adjacency matrixes used in [[SysML]] and business contexts a lot. **** # More ## Source - https://guides.sharafat.co.uk/documents/Graph_Theory_for_Dummies.pdf
