Nodes of different colours represent the following:
Solid arrows point from a parent (sub)module to the submodule which is descended from it. Dashed arrows point from a module being used to the module or program unit using it. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

| logical, | intent(in) | :: | FirstHVACIteration | |||
| integer, | intent(in) | :: | ZoneNum | |||
| integer, | intent(in) | :: | ZoneNodeNum | |||
| integer, | intent(inout) | :: | CompIndex | 
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
