Re: ConTeXt +Tioga

[andrea valle <valle@di.unito.it>]

As far as we are discussing about graphics, actually my favorite and 
quick (and powreful) solution to produce pdf graphics not TeX-related 
is to use the graphic facilities of R, generating automatically scripts 
with code
(http://www.r-project.org/).
