Hi all,

i am writing a paper in college about optimization problems in Julia.  
Regarding a network flow problem i would like to create a colored graph for visualization.  
I managed to visualize the nodes and edges with the corresponding values using the Lightgraphs package but I am stucked at coloring the nodes. There are different stages in the network (production, further processing, logistics, market) and I would like to color each node depending on the stage of this node. Is there any possibility for doing so with Lightgraphs?  
I found this topic([https://github.com/JuliaGraphs/LightGraphs.jl/issues/773](https://github.com/JuliaGraphs/LightGraphs.jl/issues/773) [https://github.com/JuliaGraphs/LightGraphs.jl/pull/844](https://github.com/JuliaGraphs/LightGraphs.jl/pull/844)) but no documentation on how to use this.

For any help I would be really grateful.

Best regards  
Alex

If you’re using GraphPlot.jl, the option to color the nodes is `nodefillc` and `nodestrokec` (see [GitHub - JuliaGraphs/GraphPlot.jl: Graph visualization for Julia.](https://github.com/JuliaGraphs/GraphPlot.jl#arguments) for more details).

If you’re not using GraphPlot, what _are_ you using?

Yes, i am using GraphPlot.  
This is much easier than I thought, thank you very much!!
