NAME

       springgraph - renders a graph from a .dot file

SYNOPSIS

       springgraph [OPTIONS] < input-file.dot > output-file.png

DESCRIPTION

       Springgraph will read in a .dot file description of a graph, which, for each node, specifies its name and which other nodes it is connected
       to, and then renders a graph. The output is a PNG file. Each node is drawn as an ellipse, and each connection is drawn  as  an  arrow.  The
       node  placement	is  a  result of all of the nodes moving away from each other, while all nodes which are connected move toward each other.
       This movement is repeated until it stabilizes.

       Springgraph was written as an alternative to neato, which is part of graphviz. It attempts to read the same .dot files  used  by  graphviz,
       but  currently  only  supports  a limited number of node attributes (label and fillcolor) and can only handle two nodes per edge definition
       ("node1 -> node2", not "node1 -> node2 -> node3").

OPTIONS

       springgraph accepts the following options:

       -p	       Create a file that can be rendered with POV-Ray

       -v	       create a VRML file

       -s	       this option specifies the scale. All of the node locations are multiplied by this. Increase the	scale  to  eliminate  node
		       overlaps. Decrease the scale to make the graph smaller.

       -t	       make the background of the resulting image transparent.

       -b	       set  background color of image, specify it in the form RRGGBB, in hex digits, e.g. FFFFFF is white, 000000 is black, FF0000
		       is red, ...

       -l	       set the line color, same format as the background color

       -h	       display usage synopsis

EXAMPLE

	digraph {
	 "rene" -> "myon";
	 "mvo" -> "rene";
	}

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.
