Scope:
Develop network graphs to visually represent the coupling between modules. This visualisation will help in identifying tightly coupled modules and analysing their interactions.
The Modstat tool can generate module-level coupling output using the following command: ./dist/modstat. Running this command produces an output that when parsed by libraries like PyViz to create network graphs.
