| <graph> |
encodes a graph, which is a collection of nodes, and arcs which
connect the nodes. |
| Attributes |
(In addition to global attributes
and those inherited from chunk)
| type |
describes the type of graph. |
|
Datatype: CDATA |
|
Suggested values include:
| undirected |
undirected graph |
| directed |
directed graph |
| transition network |
a directed graph with distinguished initial and final nodes |
| transducer |
a transition network with up to two labels on each arc |
|
|
Default: #IMPLIED |
| Note |
If type=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=directed
(or any other value which implies directionality), then the
adjFrom and adjTo attributes should be used,
instead of the adj attribute.
|
| label |
gives a label for a graph. |
|
Datatype: CDATA |
|
Values: A character string. |
|
Default: #IMPLIED |
| order |
states the order of the graph, i.e., the number of its nodes. |
|
Datatype: CDATA |
|
Values: A positive integer. |
|
Default: #IMPLIED |
| size |
states the size of the graph, i.e., the number of its arcs. |
|
Datatype: CDATA |
|
Values: A non-negative integer. |
|
Default: #IMPLIED |
|
| Example |
<graph id="cug1"
rend="LABEL-PLACE bottom center NODE-FRAME none ARC solid line"
type="undirected" label="Airline Connections in Southwestern USA"
order="5" size="4">
<node id="lax" label="LAX" degree="2"/>
<node id="lvg" label="LVG" degree="2"/>
<node id="phx" label="PHX" degree="3"/>
<node id="tus" label="TUS" degree="1"/>
<node id="cib" label="CIB" degree="0"/>
<arc from="lax" to="lvg"/>
<arc from="lax" to="phx"/>
<arc from="lvg" to="phx"/>
<arc from="phx" to="tus"/>
</graph>
