A graph consists of a set of vertices and a set of links.
I think you should have a table for vertices and a able for links.
Something like this:
db.define_table('vertex',SQLField('metadata'))
db.define_table('link',SQLField('source',db.vertex),SQLField
('dest',db.vertex),SQLField('metadata'))
db.link.source=IS_IN_DB(db,'db.vertex.id')
db.link.dest=IS_IN_DB(db,'db.vertex.id')
from gluon.tools import Crud
crud=Crud(globals(),db)
def build():
form1=crud.create(db.vertex,next=URL(r=request))
form2=crud.create(db.link,next=URL(r=request))
vertices=db(db.vertex.id>0).select()
links=db(db.link.id>0).select()
return dict
(form1=form1,form2=form2,vertices=vertces,links=links)
