Practical-9

 Aim: Execute queries in the Neo4j graph database and in Gephi tool perform the operations of loading csv data, running graph statistics scripts and displaying various graphical layouts.

Theory: 

What is graph data?

Graph is non linear data structure as it consist of the source value to the targeted value. As Source value and target values are Nodes and they are connected by edges.   

How it is stored?

Graph is stored in the form of Nodes and Edges with their edges weight.

How to visualize graph?

We can Visualize graph with connecting Nodes by Edges also we can visualize with the graph visual tools.

Neo4j:

A tool similar to database which takes the query and generates the graph for the dataset given. It has two options for importing of data Own data and already given data.

Gephi Tool:

    Gephi is a tool for data analysts and scientists keen to explore and understand graphs. Like Photoshop™ but for graph data, the user interacts with the representation, manipulate the structures, shapes and colors to reveal hidden patterns

Import data set:

Gives info the number of nodes and number of edges giving other info while importing the dataset
