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:

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

I did not actually download your notebook. I just tested what happens with more than 999 vertices. Now I tried your notebook and I believe there is (yet another!) bug in Mathematica's graph functionality. That is why you get the pink boxes. You should report this to Wolfram Support (please do). `VertexShapeFunction -> "Circle"` should be used in `Graph`, as you have. This code works: Graph[Range[1000], {}, VertexShapeFunction -> "Circle", VertexSize -> 1/2] The default size seems to be too small for the vertices to be visible. As a workaround for your case, you can use `VertexShapeFunction -> (Disk[#1,#3]&)`. This sort of styling will be much easier to do in the next version of the IGraph/M package, by chaining `IGVertexMap` functions. I plan to release a preview version on the weekend that you can play with. Until then, here's a teaser:

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!

Use VertexSize with more than 999 Vertices?
