Answer 1

There is no single answer.

• add -v to the command line to help understand where dot is getting stuck (dot -v -Txxx ...)
• try using one of the other layout engines (fdp, neato, circo, ...)
• The Dot User Guide says: For completeness, we note that dot also provides access to various parameters which play technical roles in the layout algorithms. These include mclimit, nslimit, nslimit1, remincross and searchsize.
• This web search leads to more help: mclimit OR maxiter dot
