Lab devices visualization using Graph DB

Hello! Have been exploring neo4j for the last few months, I am trying to have a visualization for our lab devices using Go bolt driver to connect to Neo4j DB and D3.js for UI.

When we have thousands of devices, it's practically not possible to show all the components in UI, the main aim is to show high-level important components and their connectivity by skipping the not-so-important components.

How can I easily show connectivity from and to important components via intermediate components?
I also need to show a path count and the status between them.

Do you have some code or additional information to share? It is easier to help provide guidance with some more specific questions / examples. There are lots of different ways to model and create UIs to represent data.
