Feature: Graphviz Configuration


  Scenario: Global Configuration
    Given I have a file named '_config.yml' with:

      {% graphviz %}
      digraph {
        A -> B;
      }
      {% endgraphviz %}
      """
    When I run jekyll build
    Then the file '_site/graphviz.html' should exist
    # Graph
