graph vs skeleton

graph

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

  • 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. 

  • 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. 

  • 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. 

  • A set of points constituting a graphical representation of a real function; (formally) a set of tuples (x_1,x_2,…,x_m,y)∈ R ᵐ⁺¹, where y=f(x_1,x_2,…,x_m) for a given function f: R ᵐ→ R . See also Graph of a function on Wikipedia.Wikipedia 

  • A morphism 𝛤_f from the domain of f to the product of the domain and codomain of f, such that the first projection applied to 𝛤_f equals the identity of the domain, and the second projection applied to 𝛤_f is equal to f. 

verb
  • To draw a graph of a function. 

  • To draw a graph. 

skeleton

noun
  • The vertices and edges of a polyhedron, taken collectively. 

  • A client-helper procedure that communicates with a stub. 

  • The system that provides support to an organism, internal and made up of bones and cartilage in vertebrates, external in some other animals. 

  • A very thin person. 

  • A frame that provides support to a building or other construction. 

  • The network of veins in a leaf. 

  • A type of tobogganing in which competitors lie face down, and descend head first. 

  • A very thin form of light-faced type. 

  • Reduced to a minimum or bare essentials. 

  • An anthropomorphic representation of a skeleton. 

  • The central core of something that gives shape to the entire structure.
