Revision/History Graph - DAG (Directed Acyclic Graph)

Is anyone aware of tools which (re)construct a DAG from Subversion
repository history and display it pretty much like today's DVCSes?
For example:

http://code.google.com/a/eclipselabs.org/p/mercurialeclipse/source/list?r=ee7ed7ec51606117613924d0662fc03086787450

https://bitbucket.org/tortoisehg/thg/changesets/9fbf6b7fe9d5

I realize this could be tricky because of the implicit branching SVN
employs, but may be it's not impossible. I imagine much of it could
be done using the copy source and merge-info data, though multiple
copy and merge sources for certain revision/changeset seem non-trivial.
