???  Of course you can!

Anyway, try 1.19, or the current CVS (if you need dashed or dotted
ellipses).  Until those files are on ftp.gnu.org again, please
download from

   http://ftp.ffii.org/pub/groff

But the \graph box can be used in a normal LaTeX document also.  The
updated pic manual page suggests to use this:

>From the (updated) pic manual page:

  To make the vbox having a positive height and a depth of zero (as
  used e.g. by LaTeX's graphics.sty), define the following macro in
  your document:

    \def\gpicbox#1{%
      \vbox{\unvbox\csname #1\endcsname\kern 0pt}}

  Now you can simply say \gpicbox{graph} instead of \box\graph.
