How can I generate some sort of call diagram from my D code?

you can compile with (dmd) -profile and run the executable. This 
produces a file called trace.log which contains timings for each 
function and a call graph. It doesn't produce a diagram and has mangled 
symbols though.

You can demangle with std.demangle, read the trace.log with descent or 
use this utility:

I haven't updated ptrace in quite a while, so I'm not sure if it still 
works.

I just noticed it is called a call graph, being directed and all.
I really just needed the visual thing and seeing that I need to get tango to
work to use ptrace (and then maybe it won't work) I really should just take
pencil and paper, I think. Also, it is only a sub-section (30 functions or so) 
I'm interested in.
Thanks anyway!

With a little persitance, I'd bet that you could make a awk/grep/sed system 
that would convert that output to a graphviz file. With a little fun using 
pragma(msg,...) and .mangleof you could even get demangled symbols.
