.SH NAME
maria-vis \- graph visualization script for maria
.SH SYNOPSIS
.B maria-vis
.SH DESCRIPTION
This manual page documents brie\(fly the
.B maria-vis
command.
.PP
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
.\" respectively.
\fBmaria-vis\fP is a \fBlefty\fP script invoked by \fBmaria\fP in
order to visually present information to the user. The script reads
commands and directives from standard input and may write \fBmaria\fP
query language commands to standard output. An end-of-file condition
on standard input terminates the script.
.br
The script is built on top of the \fBdotty\fP script that is part of
the GraphViz package. The commands prefixed with \fBvisual\fP in
\fBmaria\fP issue two kinds of commands to this script: \fInew();\fP
or \fIadd();\fP followed by a newline character and a graph definition
in the \fBdot\fP input language. The \fInew\fP function in the script
displays the graph in a new window, while the \fIadd\fP function
copies information from the graph to the last modified graph.
