graphviz

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.

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.
