Here is the program, as well as some of the results. The example files show the simulator mill (with check_constraints.hal loaded) and the simulator lathe. With emc running and halcmd on your PATH, just run net2dot to create a .dot file, or pipe net2dot to dot to render an image:
$ python net2dot.py > mymachine.dot
$ python net2dot.py | dot -Tpng > mymachine.png
Update: A new version of net2dot also understands 'linkXX' commands, so it can be used on .hal files in addition to to working from a running hal. It will infer directions from arrows when they are given. Run it like so:
$ python net2dot.py core_stepper.hal standard_pinout.hal > mill.dot
$ python net2dot.py core_stepper.hal standard_pinout.hal | dot -Tpng > mill.png
