(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.

(mathematics) A set of points constituting a graphical representation of a real function; a set of tuples ( x 1 , x 2 , … , x m , y ) ∈ R m + 1 {\displaystyle (x_{1},x_{2},\ldots ,x_{m},y)\in \mathbb {R} ^{m+1}} , where y = f ( x 1 , x 2 , … , x m ) {\displaystyle y=f(x_{1},x_{2},\ldots ,x_{m})} for a given function f : R m → R {\displaystyle f:\mathbb {R} ^{m}\rightarrow \mathbb {R} } .

(graph theory) A set of vertices (or nodes) connected together by edges; an ordered pair of sets ( V , E ) {\displaystyle (V,E)} , where the elements of V {\displaystyle V} are called vertices or nodes and E {\displaystyle E} is a set of pairs (called edges) of elements of V {\displaystyle V} . See also Graph (discrete mathematics) on Wikipedia.Wikipedia

(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.

(category theory, of a morphism f) A morphism Γ f {\displaystyle \Gamma _{f}} from the domain of f {\displaystyle f} to the product of the domain and codomain of f {\displaystyle f} , such that the first projection applied to Γ f {\displaystyle \Gamma _{f}} equals the identity of the domain, and the second projection applied to Γ f {\displaystyle \Gamma _{f}} is equal to f {\displaystyle f} .

(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.

(transitive) To draw a graph.

(transitive, mathematics) To draw a graph of a function.
