:Title: Flowchart
:Tags: Diagrams;Flowcharts;Node positioning;Nodes and shapes
:Author: Qrrbrbirlbel
:Slug: flowchart

This example flowchart uses the positioning-plus library and the
node-families library by the same author. The fit library is implicitly loaded
by positioning-plus, the backgrounds library is used to draw stuff behind
other stuff, the calc library for some coordinate calculations and the
shapes.geometric library for the ellipse shape.

This example was written by Qrrbrbirlbel answering a question on TeX.SE.

:Title: Actor Transaction Diagram

A sample of a global Actor Transaction Diagram or ATD of the 
`Design & Engineering Methodology for Organizations (DEMO) methodology`__. 
The most interesting part of the example is the definition of the custom 
``square`` arrow the and ``diamond in circle`` node shape.

**Note**: The ``square`` arrow is now available in the CVS version of PGF. 
In the example the arrow shape has been renamed to ``squarea`` to avoid conflict.
