Feature diagram with DIA

["Gomes Ludermir, P. (Pablo)" <P GomesLudermir ewi utwente nl>]

Dear all,

I have searched the mailing list archive but I could not find any kind
of answer to my following question.
I would like to draw some feature diagrams for domain modelling as in
the following document (see Figure 1):
http://homepages.cwi.nl/~arie/papers/fdl/fdl.pdf

How can I develop my own diagram? Or does anyone know if such kind of
diagram has been already developed for DIA?

Best Regards,
Pablo
