Class loaders - distribute objects by class loader

Biggest Objects - find individual objects that retain most of memory

Merged Paths - examine how objects are retained

Generations - distribute objects by time of their creation

Reachability scopes - shows objects distributed according to how/whether they are reachable from GC roots

Object Explorer - browse individual objects

Allocations - explore methods where objects were created (available only if snapshot contains recorded object allocations).
