graphviz_rプラグインでrdotテンプレートも使えるようにしてみました。プラグイン入れて、拡張子 rdot でビューを作ればおｋ。無論、インスタンス変数も受け渡し可。

# controllers/rdot_gen_controller.rb
class RdotGenController < ApplicationController
  def index
    @label1 = "<p_left> left|<p_center>center|<p_right> right"
    @label2 = "left|center|right"
  end
end

# views/rdot_gen/index.rdot
graph [:size => '1.5, 2.5']
node [:shape => :record]
node1 [:label => @label1]
node2 [:label => @label2]
node1 >> node2
node1(:p_left) >> node2
node2 >> node1(:p_center)
(node2 >> node1(:p_right)) [:label => 'record']
