Awkward helps you walk your Object Graph and output a dot file suitable for viewing in Graphviz. Awkward doesn’t know how to visit your objects, so you must teach it by implementing a subclass of Awkward::Visitor.

• May not work

class MyVisitor < Awkward::Visitor
  def visit_MyModule_MyObject object
    edge(:some_method) do
      accept object.some_method
    end
  end
end

viz = MyVisitor.new
viz.accept my_object
File.open('my_object.dot', 'w') do |f|
  f << viz.dot
end

Then, on the command line:

$ dot -Tgif -O my_object.dot # Generates an image named my_object.dot.gif

• FIX (list of requirements)

• FIX (sudo gem install, anything else)
