This is the command springgraph that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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";
}
