The Graphviz attributes documentation describes the style attribute but does not say what values it may hold:
Set style information for components of the graph. For cluster subgraphs, if style="filled", the cluster box's background is filled. If the default style attribute has been set for a component, an individual component can use style="" to revert to the normal default. For example, if the graph has
edge [style="invis"]
making all edges invisible, a specific edge can overrride this via:
a -> b [style=""]
Of course, the component can also explicitly set its style attribute to the desired value.
