= DotR - Ruby wrapper for the 'dot' utility =

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.  It supports subgraphs and full style attributes for graphs, nodes and connections (aka "edges").

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

== Example ==

{{{
#!ruby
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)) }
}}}
