====== Diagram Editor ======

The diagram editor allows you to insert and edit diagrams based on GraphViz. GraphViz (or "dot" as the program is also referred to) uses a basic script language to define diagrams. This plugin adds a dialog where one can define a diagram in this script. The dialog shows a preview of the rendered diagram and when the diagram is finished it can be inserted in a zim page as an image. You can always edit it later again by selecting "Edit Diagram" from the context menu (right-mouse-click on the diagram will show the context menu).

**Dependencies:** This plugin requires GraphViz to be installed. In specific the "dot" command should be available in the system path.

===== Example =====

For example a diagram like:

{{./diagram.png}}

Can be created by entering the following definition in the dialog:

'''
digraph G {
  foo -> bar
  bar -> baz
  baz -> foo
}
'''

For full documentation of the script language see: http://www.graphviz.org/

===== Options =====

This plugin has the following options:

* The option **Generate diagrams in SVG format** determines whether the diagrams will be generated in the SVG format. This is only enabled by default if your system supports it.
