How were the state charts drawn in Miro Samek's "Practical UML Statecharts in C/C++"

Question

What software package was used to draw the statecharts in Miro Samek's "Practical UML Statecharts in C/C++"?

Edit: Miro Samek provided excerpts from his book on his website. Page 42 of the linked PDF provides an example diagram.

Answer 1

All diagrams in the PSiCC2 book have been prepared with Microsoft-Visio 2003. The Visio stencil used in the book is available for a free download from the companion web-page to the book.

There is also a newer free graphical modeling tool called QM, which you can use to draw diagrams and export to EMF vector format as well as JPG raster format.
