<graph>

<graph> encodes a graph, which is a collection of nodes, and arcs which connect the nodes. [19.1 Graphs and Digraphs]

Attributesatt.global (@xml:id, @n, @xml:lang, @xml:base, @xml:space) (att.global.rendition (@rend, @style, @rendition)) (att.global.linking (@corresp, @synch, @sameAs, @copyOf, @next, @prev, @exclude, @select)) (att.global.analytic (@ana)) (att.global.facs (@facs)) (att.global.change (@change)) (att.global.responsibility (@cert, @resp)) (att.global.source (@source)) att.typed (type, @subtype)
typedescribes the type of graph.
Derived fromatt.typed
Status Recommended
Datatype teidata.enumerated
Note

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.

orderstates the order of the graph, i.e., the number of its nodes.
Status Optional
Datatype teidata.count
sizestates the size of the graph, i.e., the number of its arcs.
Status Optional
Datatype teidata.count
