Structure of Component Dependencies

How actually it works in this form Component Dependencies
graph TB
subgraph sg_something[“Component Alpha”];
sg_something_x(“ModuleA.Unknown”) -.-> sg_something_y(“ModuleA.Executor?”)
end

subgraph sg_otherthing["Component Beta"];
    sg_otherthing_a("Beta.Handler") --> sg_otherthing_b("Beta.Executor?") 
end

subgraph sg_different["Project-X"];
    sg_different_alpha("X.Project?")
end

sg_something_x -.-> sg_otherthing_a
sg_something_y -.-> sg_otherthing_b
sg_otherthing_b --> sg_different_alpha
