(Asking because I think there is a lot out there in terms of being able to look at raw JSON and collapse / expand individual records, but if you want something to view this is more of a network structure / hypermedia where you can visualize the network structure, it's probably going to be really dependent on how the JSON is formatted.)
As one example of a visual tool for "networks of things referencing each other in JSON", there is the cytoscape library, which is pretty awesome, and support a "JSON Graph" format. Worth looking at if you control how records go from DB to JSON
