springgraph - renders a graph from a .dot file
Contents
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").
Example
digraph {
"rene" -> "myon";
"mvo" -> "rene";
}
Name
springgraph - renders a graph from a .dot file
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
