I have just redone cc-ms.pdf in dot[1].
- Your notes are missing, because parts are difficult to read.
  Please add them yourself.
- The original documentation is very inconsistent in the usage of '.' 
  and '-'. I have done it as close to the original as possible. One 
  scheme should be selected and the .dot file adjusted.

The other graphs should probably be redone in dot too.

Kind regards,
