PRESENTATION TOPIC 
GRAPH
WHAT IS GRAPH ? 
 A GRAPH is a mathematical structure consisting of a set of 
vertices and a set of edges. 
 Node: Each element of a graph is called node of a graph 
 Edge :Line joining two nodes is called an edge 
= Vertices 
= Edeges
TYPES OF GRAPHS 
There are two types of graph : 
• Directed graph 
• Undirected graph
DIRECTED GRAPH 
• A graphs G is called directed graph if each edge has a direction.
UN DIRECTED GRAPH 
• A graphs G is called directed graph if each edge has no direction.
SOME DIFFERENT TYPES OF GRAPH 
1. Sub graph 
2. Complete graph
3. Weighted graph
REPRESENTATION OF GRAPHS 
Graphs can be represented in 2 ways : 
 Array representation
Linked list representation
