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"). +.SH OPTIONS +\fIspringgraph\fP +accepts the following options: +.TP 16 +.B \-p +Create a file that can be rendered with POV-Ray +.TP 16 +.B \-v +create a VRML file +.TP 16 +.B \-s +this option specifies the scale.
