Graphviz node style : thicker contours?

Question

I'm looking for something pretty simple I believe: I would like my nodes to have thicker contours. For example this:

node [shape="box", color="red", style="filled", fillcolor="cyan"]

should give me cyan and box-shaped nodes, with red contour. What if I want thicker red lines? I thought maybe I should use width & height attributes, but I'm not sure how to.

Thanks for your help.

You are looking for penwidth :

Specifies the width of the pen, in points, used to draw lines and curves, including the boundaries of edges and clusters. The value is inherited by subclusters. It has no effect on text.

Simply add for example penwidth=5 to the attributes.
