I'm not so sure that many graph databases use a relational database as the data store. Some use Linear Algebra representations of the graph. Some use key-value stores. Some are proprietary implementations that we'll never know exactly how the data is represented under the covers.

RecallGraph at first glance looks a bit like TerminusDB that recently featured on HN [0]. In terminusdb data is stored like code in git, and you can time travel and do branch, merge, squash, rollback, diff, blame, etc. But TerminusDB is a semantic graph database based on OWL schemas, which stores data as RDF and querying delivers JSON-LD. I will certainly give RecallGraph a closer look.
