TT></A>
attribute can be used to modify the appearance of a node.
At present, there are 8 style values recognized:
<TT>filled</TT>, <TT>invisible</TT>, <TT>diagonals</TT>, <TT>rounded</TT>.
<TT>dashed</TT>, <TT>dotted</TT>, <TT>solid</TT> and <TT>bold</TT>.
As usual, the value of the <A HREF=attrs.html#d:style><TT>style</TT></A>
attribute can be a comma-separated list of any of these. If the
style contains conflicts (e.g, <TT>style="dotted, solid"</TT>), the last
attribute wins.
