Navigating Contextual Complexity with Graph Visualization

The automatically generated system graph in Figure 4-14 represents an example instance model of a heating , ventilation , and air conditioning ( HVAC ) unit , based on elements defined by the IFC meta-model described in section 4.1 . This generated graph layout conforms to domain expectations for arranging the connections between the related air distribution loop , chilled water distribution loop , and the hot water system similar to the example in Figure 4-13 , using a simpler style . The portions of the air flow system are aligned , as they would be in an air chamber , and the cooling and heating coils are positioned relative to other components in the system .
