NAME
smyrna - interactive graph viewer
SYNOPSIS
smyrna [ -v? ] [ file ]
DESCRIPTION
smyrna is a viewer for graphs in the DOT format. It is
especially designed to handle large graphs, and allows flat
and topological fisheye views. It is assumed the input
graph has position information associated with all nodes.
Using the Graphviz convention, a node's position is given by
its pos attribute consisting of 2 or 3 floating point num-
bers separated by commas. Nodes are drawn as points and
edges as line segments.
If smyrna detects that the file contains xdot attributes, it
will use this information when drawing nodes and edges.
smyrna supports panning and zooming; node and edge selec-
tion; setting and retrieving node and edge attributes, espe-
cially colors; and node movement. The Smyrna Settings dia-
logue box available under the Edit pull-down menu gives the
user many choices for tailoring the graph view. These
include whether or not nodes/edges are drawn; what labels
are associated with nodes/edges; node size; transparency
settings for nodes/edges; parameters associated with the
topological fisheye view.
For the purposes of exploratory data analysis, smyrna pro-
vides access to the gvpr library. This allows the user to
arbitrarily query, filter or manipulate a graph. When fil-
tering or manipulating a graph, the user has the option of
performing the changes directly on the input graph, or to
create a new version with the changes.
OPTIONS
The following options are supported:
-v Verbose mode.
-? Print usage information.
By default, gc returns the number of nodes and edges.
OPERANDS
The following operand is supported:
file Name of file containing a graph in DOT format. If
no file operand is specified, the user can employ
the File pull-down menu to select a file to be
opened.

EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 If no No appropriate OpenGL-capable visual found, or if
the default attributes template graph file or the
default attributes widget graph file could not be read.
FILES
smyrna relies on numerous support files. These are usually
installed in the "share/graphviz/smyrna" directory below the
installation root. The principal files are:
template.dot
A file in DOT format specifying the default smyrna set-
tings. In particular, these are used to initialize the
settings of the Smyrna Settings dialogue box.
mouse_actions.txt
A text file specifying the mapping of concrete mouse
and keyboard events with smyrna actions such as panning
and selecting.
attr_widgets.dot
A file in DOT format specifying the bindings between
GUI widgets and smyrna parameters.
ENVIRONMENT VARIABLES
SMYRNA_PATH
allows a user to override the built-in path to the
directory containing all of smyrna's files described
above.
