        Word: grafetu [jbovlaste]
        Type: fu'ivla
  Gloss Word: edge of graph
  Gloss Word: graph in the sense of "graph theory"
  Gloss Word: network in the sense of "graph"
  Gloss Word: node in the sense of "vertex of graph"
  Gloss Word: web in the sense of "graph"
  Definition: x1 is the graph on vertices/nodes x2 (set) and edges x3 (set of
       ordered or unordered tuples of vertices in x2) and with
       additional properties x4.
       Notes: A "web"/"network". An element of x2 is a "place" in a more
       generic/abstract/metaphoric sense than spatial; must be
       discrete. Thus, webpages, family diagrams, lattices, pages in a
       book, cities and roadways on a map, etc. constitute graphs. x1
       also includes trees. Notice that both x2 and x3 are sets; an
       element of x3 is an ordered pair/2-tuple, but the order does
       not matter unless x1 is oriented, in which case the edge runs
       from the first node in the tuple to the second node in the
       tuple. x4 can include defining features, weights, etc.
       Equivalent to grafu (which is merely the gismu form of this
       word); very similar to tcana.
