SVN Branch Viewer

Question

Is there is a tool for SVN that visually shows how branches are related? I've got a couple dozen branches and it isn't clear how they were created from one-another.

Answer 1

I know only of a non-free one: SmartSVN:

But the graph feature of the latest TortoiseSVN 1.7 can help too:

Can create a graph of all revisions/commits. You can then easily see where you created a tag/branch or modified a file/folder

Since a branch is a directory in SVN, you can display the its graph and see at the path of the revision of its origin, to get an idea of the "parent" branch.
