like below fixes the issue
is there any other way of finding and drawing all possible connected planar graphs with E edge?

With graphs in SQLAlchemy, how can one find nodes that are not connected to some specific other node by an edge?

like below fixes the issue Suppose I have saved a directed graph in a table similar to the example in the SQLAlchemy documentation: http://docs.sqlalchemy.org/en/rel_0_7/orm/examples.html#directed-graphs
code :
def get_non_touching(ref_node):
    qry = session.query(Node)
    qry = qry.filter(~Node.lower_edges.any(Edge.higher_id == ref_node.node_id))
    qry = qry.filter(~Node.higher_edges.any(Edge.lower_id == ref_node.node_id))
    qry = qry.filter(Node.node_id != ref_node.node_id) # exclude node "a" itself as well
    return qry.all()

a = session.query(Node).get(1)
res = get_non_touching(a)

Hope that helps I feel pretty dumb answering my own question but that may help somebody someday.
In my "Edit 1", I was wrong about the content of $instance.

it fixes the issue Everything with a direction assigned to it is literal, as in left will always be left, right will always be right. Start and End are dependent on whether a language reads left-to-right or right-to-left, start and end matching those accordingly.
alignBaseline will align to the bottom of the text itself, where alignBottom will align to the bottom of the view. So in a view with text that has 10dp padding under it, alignBottom will align 10dp below the text, where alignBaseline will align with the bottom of the text itself.

This might help you You're constructing a hierarchy of nested objects with models in between:
code :
Model
 ⟶ List<PlanarHabitant>
     ⟶* PlanarHabitant
          ⟶ Model<House>
              ⟶ House
          ⟶ Model<Habitant>
              ⟶ Habitant
class PlanarHabitant {
  private House house;
  private Habitant habitant;
}

Does that help There is no "join". The data is already connected by way of the edge, so you simply need to traverse further along your graph to get the "CompanyName".
code :
g.V('id-of-User').out().values("CompanyName")
g.V('id-of-User').outE().
  project('eid','label','companyName').
    by(T.id).
    by(T.label).
    by(inV().values("CompanyName"))
