Diagrams are similar to textual documentation: You generally can’t auto-generate useful ones from code, unless the code has extra markup that specifies what to generate. Diagrams often present a specific perspective that emphasizes certain features while omitting others. You might have several diagrams for the same entity, each illustrating a different aspect or scenario.
The upshot is that diagrams have to be maintained in conjunction with the code and application architecture, just like textual documentation. There’s just no alternative to simply putting the work in, and making it a regular part of change management.
