You could use the native GraphPlot function to plot your Combinatorica-defined graph as follows: Needs["Combinatorica`"] g = Cycle[3]; GraphPlot[g, VertexRenderingFunction -> ({EdgeForm[{Thick, Red}], FaceForm[Yellow], Disk[#1, 0.05], Text[#2, #1]} &)] Stephen Luttrell West Malvern, UK "Murray Eisenberg" <murray at math.umass.edu> wrote in message news:fqqrql$k9j$1 at smc.vnet.net... > With Mathematica 6, I can change the default style (medium black disk) > for rendering the vertices of a Combinatorica Graph like this: > > Needs["Combinatorica`"] > > g = Cycle[3]; > ShowGraph[g, VertexStyle -> Disk[Large], VertexColor -> Red] > > But how can I, for example, change the vertex style so it is, say, a > large yellow disk with a thick red boundary?
