Node- Link Maps ◾ 21
lower- level node- link maps. The result of this approach is a nested series
of node- link maps that provide increasing levels of detail. When using this
type of drilldown approach, however, make sure that maps that are more
detailed are clearly identified and tied back to higher- level maps. One
approach for doing so as indicated earlier is illustrated in Figure2.7.
◾ Third, simply start creating a node- link map using circles and lines. Do
not forget that a single node can have multiple links tied to it. Some
purists only use straight lines to connect two nodes together, whereas
I often use a curved line when I need ...
