<graph> codifica un gráfico, es decir un conjunto de nodos y arcos que conectan los nodos. 19.1 Graphs and Digraphs

Módulo

Atributos

type

describe el tipo de gráfico

Estado	Recomendado
Tipo de datos	<rng:ref name="data.enumerated"/> data.enumerated
Suggested values include:	undirected undirected graph directed directed graph transitionNetwork a directed graph with distinguished initial and final nodes transducer a transition network with up to two labels on each arc
Nota	If type is specified as undirected, then the distinction between the to and from attributes of the <arc> tag is neutralized. Also, the adj attribute, rather than the adjFrom and adjTo attributes, should be used to encode pointers to the ends of the arcs. If type is specified as directed (or any other value which implies directionality), then the adjFrom and adjTo attributes should be used, instead of the adj attribute.

order

define el orden del gráfico, es decir, el número de sus nodos.

Estado	Opcional
Tipo de datos	<rng:ref name="data.count"/> data.count
Valores	A positive integer.

size

define la dimensión del gráfico, es decir, el número de sus arcos.

Estado	Opcional
Tipo de datos	<rng:ref name="data.count"/> data.count
Valores	A non-negative integer.
