Graphs in Centaur1.2

[menez@mimosa.unice.fr (Gilles MENEZ)]

I want to make graphs with CENTAUR, should I use PSP language approach :
node --> implemented as TREE; subject in TYPOL rules and gettree primitive ...

or should I use annotation approach :
with getannot and sendannot ....

Does my question make sense ? Are they really two solutions ? Which is the best ?
What impacts this choice will have on possible future use of graph server ?
Do you have tutorial on this ?

Thanks in advance.
