This category is for various extensions and generalizations of (simple undirected finite) graphs i.e. for graphs endowed with additional structures or parameters and for objects with definitions similar to that of a graph . Subcategories. This category has the following 3 subcategories out of 3 total.

In software engineering a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes their attributes operations (or methods) and the relationships among objects.. The class diagram is the main building block of object-oriented modeling. It is used for general conceptual modeling of the …

In the special case of a finite simple graph the adjacency matrix is a (0 1)-matrix with zeros on its diagonal. If the graph is undirected (i.e. all of its edges are bidirectional) the …

In graph theory and network analysis indicators of centrality identify the most important vertices within a graph . Applications include identifying the most influential person(s) in a social network key infrastructure nodes in the Internet or urban networks super-spreaders of disease and brain networks. Centrality concepts were first developed in social network analysis and many of the …
