graph

Definitions

• (applied mathematics) A data chart (graphical representation of data) intended to illustrate the relationship between a set (or sets) of numbers (quantities, measurements or indicative numbers) and a reference set, whose elements are indexed to those of the former set(s) and may or may not be numbers.
• (mathematics) A set of points constituting a graphical representation of a real function; (formally) a set of tuples .
• (graph theory) (formally) An ordered pair of sets ; (less formally) a set of vertices (or nodes) together with a set of edges that connect (some of) the vertices.
• (topology) A topological space which represents some graph (ordered pair of sets) and which is constructed by representing the vertices as points and the edges as copies of the real real interval [0,1] (where, for any given edge, 0 and 1 are identified with the points representing the two vertices) and equipping the result with a particular topology called the graph topology.
• (category theory) A morphism .
• (linguistics) A graphical unit on the token-level, the abstracted fundamental shape of a character or letter as distinct from its ductus (realization in a particular typeface or handwriting on the instance-level) and as distinct by a grapheme on the type-level by not fundamentally distinguishing meaning.
