Table 2.

The layouts supported in the visualization interface. The six layouts supported in the visualization interface of InteGO2

Name	Description
concentric	The concentric layout positions nodes in concentric circles.
	Users could select this layout to put the graph in the middle
	of the explorer.
breadth-first	The breadth-first layout puts nodes in a hierarchy, based
	on a breadth-first traversal of the graph. The hierarchical
	structure of the gene functional association network is
	shown in this layout.
circle	The circle layout puts nodes in a circle. From a circle layout,
	the user could easily find the nodes with high degree and
	low degree.
cose	The cose (Compound Spring Embedder) layout uses a
	force-directed simulation to lay out compound graphs.
	This layout helps the users to find the density region of the
	network.
cola	The cola layout uses a force-directed physics simulation
	with several sophisticated constraints.
grid	The grid layout puts nodes in a well-spaced grid.
