Grouping
Grouping
isusefulwhenyou'veidentifiedthatcertainnodesareassociated
because they are similar (for example, extension cord and power strip) or
because they have been strongly clustered together (for example, topics).
In this case, some graph software will allow items to be grouped together.
Ideally, a node that represents a group of items should be visually distinct
from other nodes such as different shapes.
