```node_graph.html``` file will be split into three file which indicates the **Concept graph,Collection graph** and **Dependency graph**

	1) Concept Graph (node_concept.html)
		- This graph will show the all relation of that page.
		- Feature's
			i)		Use Shift+Click to Stick the Node.
			ii)		Use Ctrl+Click to Expand/Collapse the Node.
			iii)	Using check box to Filter the Graph.

	2) Collection Graph (node_collection.html)
		- This graph will show the only collection set
		- Feature's
			i)		Use Shift+Click to Stick the Node.
			ii)		Use Ctrl+Click to Expand/Collapse the Node.

	3) Dependency Graph (node_dependancy.html)
		- This graph will show the dependency node(Prior Node).
		- Feature's
			i)		Use Shift+Click to Stick the Node.
			ii)		Use Ctrl+Click to Expand/Collapse the Node.
