Here’s a template that demonstrates how to use Fibery to create graphical representations of the entities and their relationships (a stopgap solution until the whiteboard functionality is completed )
In this example, I am modelling a bill of materials (since this is something I personally find useful) but the concept can be generalised to any set of entities/relations. Each item has a URL that, when clicked, produces a diagram of the ‘downstream’ hierarchy.
Hope some people might find it useful
UPDATE: see below for what it looks like when you open it (thanks Oshyan)
