In graph theory, a graph is a pairwise compatibility graph (PCG) if there exists a tree and two non-negative real numbers < such that each node ′ of has a one-to-one mapping with a leaf node of such that two nodes ′ and ′ are adjacent in if and only if the distance between and are in the interval [,].
Equivalently, a comparability graph is a graph that has a transitive orientation, [3] an assignment of directions to the edges of the graph (i.e. an orientation of the graph) such that the adjacency relation of the resulting directed graph is transitive: whenever there exist directed edges (x,y) and (y,z), there must exist an edge (x,z).
Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.

Isometric graph paper or 3D graph paper is a triangular graph paper which uses a series of three guidelines forming a 60° grid of small triangles. The triangles are arranged in groups of six to make hexagons. The name suggests the use for isometric views or pseudo-three-dimensional views.
JTC 1 is responsible for international Information Technology standards. GQL is intended to be a declarative database query language, like SQL. The 2019 GQL project proposal states: "Using graph as a fundamental representation for data modeling is an emerging approach in data management.
Maker-checker (or Maker and Checker or 4-Eyes) is one of the central principles of authorization in the information systems of financial organizations. The principle of maker and checker means that for each transaction, there must be at least two individuals necessary for its completion. While one individual may create a transaction, the other ...
