Auto-populate a canvas with related resources

I’ve been looking for a good way to visualise assets that are connected with relationships in CDF. A birds-eye graph-like visualisation of how our data is organized. And I think Canvas could work as a good platform for it. 

Say, for example, that I add a powerplant to my canvas, I would have loved to be able to by the click of a button add all related assets (perhaps only assets of a certain type) to the canvas, and have a connection drawn between them, and even a text-label indicating the type of relationship. Then, if I later add another asset to the canvas, I could get labeled connectors between this new asset, and the assets that already existed in the canvas. 

This could even be implemented with some sort of auto-organization of the canvas, where assets (or other resources) that are more closely connected gravitate towards each other.
