Hi there,
Displaying Cross Model Relations (CMR), which allows applications in different models to be related, is an area that our Juju team has always been trying to explore and keep the visual complexity to a minimum.
Over the last 2 iterations, we started some user research and held a workshop session to ideate solutions. Thanks again to those who contributed insights to this topic! 
This iteration, we have completed the MVP version of the CMR wireframes. We would like to share this with you to gather some feedback and comments!

Model details > Relation view
Under a specific ‘Relation’ view, together with all inter-model relations, CMRs of this model (both Provided offers and Consumptions) with their connection status and remote model details will be available.

Relations in the App panel
Both Inter-model relations and CMRs provided by a specific application will also be displayed in the app panel, giving more context of the app’s status.
We will continue to hear your feedback and to polish the design. Please feel free to share your thoughts here!
Thank you,
