Well, they are not supported by RDF/XML, which (unfortunately) is the main serialization format of RDF. Named graphs ARE supported by most triplestores, but they are mostly already reserved for other uses, like the representation of provenance based on the RDF files that the triples were loaded from. I think we are also lacking a standard vocabulary for graph - subgraph relations, which would be needed if we want to represent graphs within graphs.
