Are there any SVN-visualizers (branche structures)?

We use branching a lot and it helps secure and improve development, however it requires frequent, obvious maintenance, like merging. If you neglect this for a longer period of time or stop working on branches and let them become dust, it can be rather difficult to keep track which branches are created from where, what has been merged and what should’ve been deleted. Because of that, I was wondering whether SVN-branche visualizers exist?  It doesn’t have to be special, at all. If such thing does not exists, can this ‘easily’ be created with the MxTeamserver-API? I’d suppose it could?
