Hello @Ajinkya,
welcome to this moderated Azure community forum.
This feels to be the same question as seen here.
Having a relationship only is not enough for a 'parent' to change when a child changes.
You need to change any of the 'main-circuit' properties based on the relationship by 'graph traversal'.
Then the elements visualizating the parent can be attached and changes of the property can be visualized.
