Noun
graph (plural graphs)
- (applied mathematics, statistics) 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.
- Hyponyms: bar graph, line graph, pie graph
- (mathematics) A set of points constituting a graphical representation of a real function; (formally) a set of tuples , where for a given function . See also Graph of a function on Wikipedia.Wikipedia

- Let us take any point of the first graph, for example, , that is, the point .

- (graph theory) A set of vertices (or nodes) connected together by edges; (formally) an ordered pair of sets , where the elements of are called vertices or nodes and is a set of pairs (called edges) of elements of . See also Graph (discrete mathematics) on Wikipedia.Wikipedia
- Hyponyms: directed graph, undirected graph, tree
- 1973, Edward Minieka (translator), Claude Berge, Graphs and Hypergraphs, Elsevier (North-Holland), [1970, Claude Berge, Graphes et Hypergraphes], page vii,
- Problems involving graphs first appeared in the mathematical folklore as puzzles (e.g. Königsberg bridge problem). Later, graphs appeared in electrical engineering (Kirchhof's Law), chemistry, psychology and economics before becoming a unified field of study.
- 1997, Fan R. K. Chung, Spectral Graph Theory, American Mathematical Society, page 1,
- Spectral graph theory has a long history. In the early days, matrix theory and linear algebra were used to analyze adjacency matrices of graphs. Algebraic methods are especially effective in treating graphs which are regular and symmetric.
- (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 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.
- Synonym: topological graph

- First, let us define its 1-dimensional analog, that is, a topological graph. A graph is a 1-dimensional stratified topological space with finitely many 0-strata (vertices) and finitely many 1-strata (edges). […] A graph such that any vertex belongs to at least two half-edges we call an s-graph. Clearly the boundary of a surface with marked points is an s-graph.
- A morphism of graphs is a continuous epimorphic map of graphs compatible with the stratification; i.e., the restriction of to any open 1-stratum (interior of an edge) of is a local (therefore, global) homeomorphism with appropriate open 1-stratum of .
- (category theory, of a morphism f) A morphism from the domain of to the product of the domain and codomain of , such that the first projection applied to equals the identity of the domain, and the second projection applied to is equal to .
- (linguistics, typography) 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.
- Synonym: glyph
Usage notes
- In mathematics, the graphical representation of a function sense is generally of interest only at an elementary level.
- Nevertheless, the term vertex-edge graph is sometimes used in educational texts to distinguish the graph theory sense.
- (points constituting a graphical representation of a function):
- A graph is similar to, but not the same as a (real) function (as defined formally).
- The function is a set of ordered pairs , where is a point in and is a point in .
- A graph of is a set of points (represented as n-tuples) .
- A graph is similar to, but not the same as a (real) function (as defined formally).
- (graph theory):
- A graph may be defined such that the elements of are ordered pairs or unordered pairs.
- If the pairs are unordered, may be called an undirected graph and the elements of are called edges.
- If the pairs are ordered, is called a directed graph or digraph and the elements of may be called arcs; the notation is sometimes used.
- If the two vertices of an edge represent the same point, the edge may be called a loop.
- A graph may be defined such that the elements of are ordered pairs or unordered pairs.
