==== definition ====
x<sub>1</sub> is the graph on vertices/nodes x<sub>2</sub> (set) and edges x<sub>3</sub> (set of ordered or unordered tuples of vertices in x<sub>2</sub>) and with additional properties x<sub>4</sub>.
==== 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|grafu]] (which is merely the gismu form of this word); very similar to [[tcana|tcana]].
==== jargon type ====
Graph theory (mathematics, computer science); commonly applicable in laic, especially in Lojban.
