MARIA-VIS(1)						      General Commands Manual						      MARIA-VIS(1)

NAME

       maria-vis - graph visualization script for maria

SYNOPSIS

       maria-vis

DESCRIPTION

       This manual page documents briefly the maria-vis command.

       maria-vis  is  a  lefty script invoked by maria in order to visually present information to the user.  The script reads commands and direc-
       tives from standard input and may write maria query language commands to standard output.  An end-of-file condition on standard input  ter-
       minates the script.
       The  script is built on top of the dotty script that is part of the GraphViz package.  The commands prefixed with visual in maria issue two
       kinds of commands to this script: new(); or add(); followed by a newline character and a graph definition in the dot input  language.   The
       new  function  in the script displays the graph in a new window, while the add function copies information from the graph to the last modi-
       fied graph.

AUTHOR

       This manual page was written by Marko Makela <msmakela@tcs.hut.fi>.  The maria-vis script and the visualization option  were  designed  and
       implemented by Marko Makela.  Please see the copyright file in /usr/share/doc/maria for details.
