Details
The getDefaultAttrs
function generates a four element list
(elements being graph, cluster, node and
edge). Contained in each is another list where the element
names correspond to attributes and the value is the value for that
attribute. This list can be used to set global attributes in
Graphviz, and the exact list returned by getDefaultAttrs
represents the values that are used as basic defaults.
The checkAttrs
function can be used to verify that a global
attribute list is properly formed.
