= DotR

DotR is a tiny library that makes it easy to construct directed
graphs in a variety of graphic formats using the 'dot' utility from
the Graphviz suite of programs.

In order to use DotR you must have Graphviz installed.
See http://www.graphviz.org for installation instructions and examples
of the output that is possible.

== Example

 d = DotR::Digraph.new do |g|
   g.node('node1') do |n|
     n.label = "MyLabel"
     n.fontsize="8"
   end
   g.node('node2', :label => 'SecondNode') do |n|
     n.connection('node1', :label => 'relates to')
   end
 end

 File.open('diagram.png', 'w') { |f| f.write(d.diagram(:png)) }
