As some people have noticed, I have committed a statistical profiler
that is similar in style to profiles like gprof. This is not finished
yet -- the plan is to have a GUI front end to conveniently visualize
the call graph, and make that front end available as a DrScheme tool.
I have most of the GUI done, but I'm stuck on getting a sane layout
algorithm. I've tried to find information about the Sugiyama
algorithm for graph layout, which is (IIUC) the basis for the layout
that `dot' (from the graphviz suite) is doing -- but I'm stuck on some
of the obscure details.
In case anyone knows about graph layout algorithms, please contact me
off-list. Alternatively, if someone has a copy of
Graph Drawing: Algorithms for the Visualization of Graphs
Tollis, Di Battista, Eades & Tamassia
then please contact me too. (As much as I looked, this looks like it
might have a usable description of the algorithm.)
