Mathematica Version 11.1/ Windows 10 I'm working om a dataset with 4000+ Vertices and wanted to make some of the Vertices a bit larger. After spending a lot of time I found some suggestions like here: http://community.wolfram.com/groups/-/m/t/45871 But it seems that the VertexSize is limited to a maximum of 1000 Vertices. I couldn't find any documentation to such a limit and I would really think it's a pity to find this is bug. So perhaps there's a workaround. (The code is clumsy but I found it to be the most predictable) > h = RandomGraph[{999, 800}, ImageSize -> {800, 800}] vertexdata = {VertexList[h], Rescale@BetweennessCentrality[h]/50}\[Transpose]; vertexes = Property[#[[1]], {VertexStyle -> RandomChoice[{ Yellow, Red, Blue}], VertexSize -> Scaled[#[[2]]]}] & /@ vertexdata; Graph[vertexes, EdgeList[h]] Now I change the number of vertices to 1000 and the Graphs is shown directly with small vertices (points) I execute the same code and the result is not as desired. Only the colors are changed but not the size. Attachments:

Actually, this may not be a bug. `VertexSize -> Scaled[s]` is not a documented syntax. It does happen to work in some cases, but that is just a coincidence. The correct usage is `VertexSize -> {"Scaled", s}`. This evaluates: GraphElementData["Circle"][{0, 0}, name, {.5, .5}] But this doesn't: GraphElementData["Circle"][{0, 0}, name, Scaled[{.5, .5}]] The sizes passed to the vertex function are expected to be a pair of numbers, not a `Scaled` form. The `VertexSize -> {"Scaled", s}` specification still allows for scaled sizes, but translates these to plain numbers before passing them to the vertex shape function. Another comment: with either `VertexShapeFunction -> "Circle"` or `VertexShapeFunction -> (Disk[#1, #3]&)`, you may want to add `EdgeForm[Black]` to the vertex style.

I only saw your post after I posted mine :) Looks great! Will definitely play with the package and will post my results. What I also see is that when I use the VertexSize -> x with property[] it will show the Circle or Square etc on top of the Graph. This causes large VertexSizes to overlap with smaller vertices when they are close. I haven't found an option yet to get the edges in sync with the space reserved for the VertexSize. When I look at your picture I also see that overlap. It seems that when you use Graph[...,VertexSize->x,...] it uses the x size for the rendering of the complete Graphs and afterwards it will put the Vertexes specifically defined with VertexSize on top of the space x. Thx for your help. Much appreciated!

Hi Scabolcs, It seems that VertexSize-> Scaled[...] is causing trouble with higher vertex numbers. Will play a bit more :)

Use VertexSize with more than 999 Vertices?
