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 numbers 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 selection; setting and retrieving node and edge attributes, especially colors; and  node
       movement.   The	Smyrna	Settings  dialogue 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 provides access to the gvpr library. This allows the user to arbitrarily query, fil-
       ter or manipulate a graph. When filtering 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 settings.  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.

NAME

       gvgen - generate graphs

SYNOPSIS

       gvgen  [  -d?   ] [ -cn ] [ -Cx,y ] [ -g[f]x,y ] [ -G[f]x,y ] [ -hn ] [ -kn ] [ -bx,y ] [ -pn ] [ -sn ] [ -Sn ] [ -tn ] [ -Tx,y ] [ -wn ] [
       -ooutfile ]

DESCRIPTION

       gvgen generates a variety of simple, regularly-structured abstract graphs.

OPTIONS

       The following options are supported:

       -c n   Generate a cycle with n vertices and edges.

       -C x,y Generate an x by y cylinder.  This will have x*y vertices and 2*x*y - y edges.

       -g [f]x,y
	      Generate an x by y grid.	If f is given, the grid is folded, with an edge attaching each pair of	opposing  corner  vertices.   This
	      will have x*y vertices and 2*x*y - y - x edges if unfolded and 2*x*y - y - x + 2 edges if folded.

       -G [f]x,y
	      Generate	an  x by y partial grid.  If f is given, the grid is folded, with an edge attaching each pair of opposing corner vertices.
	      This will have x*y vertices.

       -h n   Generate a hypercube of degree n.  This will have 2^n vertices and n*2^(n-1) edges.

       -k n   Generate a complete graph on n vertices with n*(n-1)/2 edges.

       -b x,y Generate a complete x by y bipartite graph.  This will have x+y vertices and x*y edges.

       -p n   Generate a path on n vertices.  This will have n-1 edges.

       -s n   Generate a star on n vertices.  This will have n-1 edges.

       -S n   Generate a Sierpinski graph of order n.  This will have 3*(3^(n-1) - 1)/2 vertices and 3^n edges.

       -t n   Generate a binary tree of height n.  This will have 2^n-1 vertices and 2^n-2 edges.

       -T x,y Generate an x by y torus.  This will have x*y vertices and 2*x*y edges.

       -w n   Generate a path on n vertices.  This will have n-1 edges.

       -o outfile
	      If specified, the generated graph is written into the file outfile.  Otherwise, the graph is written to standard out.

       -d     Make the generated graph directed.

       -?     Print usage information.

EXIT STATUS

       gvgen exits with 0 on successful completion, and exits with 1 if given an ill-formed or incorrect flag, or if  the  specified  output  file
       could not be opened.
