bool

For the bool type,

TRUE values are represented by "true" or "yes" (case-insensitive), true and any non-zero integer
FALSE values by "false", "no" or empty string (case-insensitive), false and zero.

Example

graph[:center] = "true"

graph[:center] = true

graph[:center] = 23

TODO: Remove

spliteType or point

spline ( ';' spline )* where spline = (endp)? (startp)? point (triple)+ and triple = point point point and endp = "e,%f,%f" and startp = "s,%f,%f"

If a spline has points p1 p2 p3 ... pn, (n = 1 (mod 3)), the points correspond to the control points of a B-spline from p1 to pn. If startp is given, it touches one node of the edge, and the arrowhead goes from p1 to startp. If startp is not given, p1 touches a node. Similarly for pn and endp.

Transform to pretty up the SVG output

For more information, see www.hokstad.com/making-graphviz-output-pretty-with-xsl.html and www.hokstad.com/making-graphviz-output-pretty-with-xsl-updated.html

You can use the :nothugly option to GraphViz#output :

graph.output( :svg => "myGraph.svg", :nothugly => true )

Or directly on an SVG output graph :

GraphViz.nothugly( "myGraph.svg" )

# File lib/graphviz/nothugly.rb, line 33
def self.nothugly( file, save = true )
  xsl = File.join( File.dirname(File.expand_path(__FILE__)), "nothugly", "nothugly.xsl" )
  out = self.send(XSLT_METHOD, file, xsl)

  if save
    fname = File.join( File.dirname(File.expand_path(file)), File.basename(file))
    File.open( fname, "w" ) { |io|
      io.print out
    }
  else
    return out
  end
