Graphics in groff

The GNU pic preprocessor is able to generate graphics using the following syntax:

.PS
<pic syntax>
.PE

View the pic syntax reference from here

A great way to add graphics/diagrams is to use the software called xfig. Draw anything you like in it and export it as TPIC. Then open the exported files and copy paste the pic syntax on the .PS .PE block.
