There isn't one DNSCrypt graph. It's a forest of graphs that, in the event DNSCrypt became mainstream, would effectively converge. But, unlike DNSSEC, DNSCrypt doesn't require universal adoption to provide value.
DNSSEC provides no value at all until graph coverage is reached, and even then provides absolutely no privacy.
