# Graph - Data Structure (Physical Representation)

## About

A graph is represented generally in a physical data structure

## Format

### Two set

The graph is composed of two set.

Node
a
b
c
Node adjacent to Node
a b
a c
b a
b c
c a
c b

### Adjacency list

The graph is composed of set.

 Node a b c
Node adjacent to Nodes
a b,c
b a,c
c a,b

### Adjacency matrix

Adjacency matrix is a matrix of adjacent vertices where the coordinates (x,y) may be stored in a set

a b c
a 0 1 1
b 1 0 1
c 1 1 1
