Hi all org-mode gurus,
I am trying to generate a deck of slides using Emacs/org-mode /beamer &
some companion tools (graphviz & plantuml).
I have a problem to set the dimensions for the graphviz (or plantuml)
generated pictures.
Whatever the version used (tested 8.2.10-30 or 8.3-beta from git) and
whatever the option (ATTR_LATEX set) the TEX file generated does not
contain the right scaling options.

Here is a generated TEX file (very short) :
% Created 2015-02-09 Mon 21:54

Obviously I am doing something wrong , but what ?

Thanks for your help
Kind regards
