graphviz

Module: graphviz_filter

This Drupal filter allows writing Graphviz DOT syntax directly inside a node, to get the graph image when the node is displayed. Pretty useful for geeky types who use Drupal as their notebook.

Check it out: http://drupal.org/project/graphviz_filter

Module: workflow_graph

This little module produces graph diagrams out of workflows, useful for documentation purposes. It uses Graphviz for the actual graph generation.

It currently generates two distinct kinds of graphs:

  • One for the workflow definition, showing all workflow states, the transitions linking them, and the roles allowed to perform those transitions.
  • One for a workflow instance history, i.e. the path that a workflow took for a specific node.
