Creating a complex fishbone diagram
With a little bit of work one create a macro \subbranch, such that for example
\subbranch{met}{2cm}{foobar}{1}{a,b,c,d}
makes a subbranch belonging to the met branch, starting 2cm from the spine, with the label foobar, placed above the branch (-1 would place it below the branch), having the leaves a,b,c,d.
It's quite possible that better/easier interfaces could be defined, but this may serve as an example at least.

As it happens, I have been working on a similar format, which I have extended to address this question. The code, though extensive, is relatively straightforward and commented.
