Options for vertices

This post is an update for this post from my old blog, which did not work with the newer versions of tkz-berge. The changes are:

• instead of \tikzstyle{every node} = [node distance=1.5cm] one now has to use the macro: \SetGraphUnit{1.5},
• the macro \Vertices needs now an extra argument: {line} (another useful option here is {circle})
• the macro \Edges in line 16 needs the extra option local, in order for the other options (the color red) to work.

\begin{tikzpicture}
  \SetVertexNormal[LineColor=brown]
  \Vertex[x=0,y=2.5,style=orange,LabelOut=true,Lpos=90]{A}
  {\SetGraphUnit{1.5}
    \Vertices[x=1.5,y=4,dir=\SO,LabelOut=true,Ldist=5pt]{line}{B,C,D}}
  \Vertices[x=3,y=5,dir=\SO,style={shape=coordinate}]{line}{E,F,G,H,I,J}
  \Vertices[x=4.5,y=5,dir=\SO,style={font=\bfseries}]{line}{K,L,M,N,O,P}
  {\SetGraphUnit{1.5}
    \Vertices[x=6,y=4,dir=\SO,
    style={line width=2pt,
      inner sep=0pt,
      text=purple,
      fill=yellow,
      minimum size=12pt}]{line}{Q,R,S}}
  \Vertex[x=7.5,y=2.5,style={shape=rectangle,blue}]{T}
  \Edges[local,color=red,lw=2pt](A,B,E,K,Q,T,S,P,J,D,A)
  \Edges(B,G,L,R,T)
  \Edges(D,H,O,R)
  \Edges(A,C,F,M,Q)
  \Edges(C,I,N,S)
  \foreach \x/\y in {E/F,G/H,I/J,K/L,M/N,O/P}
  {\Edge(\x)(\y)}
  \Edge[style={bend left}](G)(N)
  \Edge[style={bend right}](A)(T)
\end{tikzpicture}

UPDATE For some reason I do not understand, the code above does not work with an updated installation of TeX Live 2011. (It worked for me with the TeX Live 2009 distributed in Ubuntu repositories). The following code produces the intended picture. Until it is figured out why the options to the \Vertex macro do not work well, it seems to be more predictable to use commands instead of options to the macro.

Such commands are defined starting at line 72 of tkz-graph.sty.

\begin{tikzpicture}
  \SetVertexNormal[LineColor=brown]
  {\renewcommand{\VertexLightFillColor}{orange}
    \Vertex[x=0,y=2.5,style=orange,LabelOut=true,Lpos=90]{A}}
  {\SetGraphUnit{1.5}
    \Vertices[x=1.5,y=4,dir=\SO,LabelOut=true,Ldist=5pt]{line}{B,C,D}}
  {\renewcommand{\VertexShape}{coordinate}
    \Vertices[x=3,y=5,dir=\SO]{line}{E,F,G,H,I,J}}
  \Vertices[x=4.5,y=5,dir=\SO,style={font=\bfseries}]{line}{K,L,M,N,O,P}
  {\SetGraphUnit{1.5}
    \renewcommand{\VertexLineWidth}{2pt}
    \renewcommand{\VertexInnerSep}{0pt}
    \renewcommand{\VertexTextColor}{purple}
    \renewcommand{\VertexLightFillColor}{yellow}
    \renewcommand{\VertexInterMinSize}{12pt}
    \Vertices[x=6,y=4,dir=\SO]{line}{Q,R,S}}
  {\renewcommand{\VertexShape}{rectangle}
    \renewcommand{\VertexLightFillColor}{blue}
    \Vertex[x=7.5,y=2.5]{T}}
  \Edges[local,color=red,lw=2pt](A,B,E,K,Q,T,S,P,J,D,A)
  \Edges(B,G,L,R,T)
  \Edges(D,H,O,R)
  \Edges(A,C,F,M,Q)
  \Edges(C,I,N,S)
  \foreach \x/\y in {E/F,G/H,I/J,K/L,M/N,O/P}
  {\Edge(\x)(\y)}
  \Edge[style={bend left}](G)(N)
  \Edge[style={bend right}](A)(T)
\end{tikzpicture}
