Yeah, you can keep your children quiet while they watch the animated CFG
and continue our debugging session... :-)

Well, neato deals with the positioning of the nodes and edges in a
generic graph. It's easy to handle the simple cases, but once you start
having tens or hundreds of nodes and edges with different sizes and
properties it becomes a mess (neato deosn't get it right either
sometimes, but it's the best free tool I have and no, I'm not going to
write a replacement, at least not in the foreseable future:-).
