Graphviz - 什么是有效的样式属性？
Graphviz - What is a valid style attribute?
Graphviz attributes documentation 描述了样式属性，但没有说明它可能包含的值：
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.

如果仔细观察，same documentation page 还指定了一个名为 style 的 Type 来描述有效的样式。摘录：
At present, the recognized style names are "dashed", "dotted",
"solid", "invis" and "bold" for nodes and edges, "tapered" for edges
only, and "filled", "striped", "wedged", "diagonals" and "rounded" for
nodes only. The styles "filled", "striped" and "rounded" are
recognized for clusters. The style "radial" is recognized for nodes,
clusters and graphs, and indicates a radial-style gradient fill if
applicable.
