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.
SEE ALSO
dot(1), dotty(1), lefty(1), maria(1).
