fillcolor
type: color | colorList, default: lightgrey (nodes) , black (clusters)
Color used to fill the background of a node or cluster
assuming style=filled, or a filled arrowhead.
If fillcolor is not defined, color is
used. (For clusters, if color is not defined,
bgcolor is used.) If this is not defined,
the default is used, except for
shape=point or when the output
format is MIF,
which use black by default.
If the value is a colorList, a gradient fill is
used. By default, this is a linear fill; setting style=radial will
cause a radial fill. At present, only two colors are used. If the second
color (after a colon) is missing, the default color is used for it.
See also the gradientangle attribute
for setting the gradient angle.
Note that a cluster inherits the root graph’s attributes if defined.
Thus, if the root graph has defined a fillcolor, this will override a
color or bgcolor attribute set for the cluster.
