I am fairly new to Julia but I am amazed and I started using GraphPlot. I have an idea for improvement and I would also really like to contribute with this via a PR.
However, since I am quite new to github also, I want to discuss my idea with you before going into action (and start learning how to use github properly regarding PRs meanwhile).
Mixed graphs:
It could be nice if GraphPlot could do mixed graphs too.
I think a simple and fine implementation could be via an individual mapping of the edges. In a lot of plotting cases, you have already done your mapping.
The origin of this issue, e.g., was that I wanted to plot the optimization of a transport model. I had all the flows in the graph mapped to an edge color corresponding to a flow/capacity-ratio:
Here, it could just be nice to write something like: gplot(g,arrowlengthfrac=[abs(flow[i]) > 0 ? 0.1 : 0 for i in 1:num_of_edges])
And thereby avoiding the arrows of all the grey edges, which just disturbs the image.
I have looked into plot.jl and lines.jl, and it seems doable without too much effort and without mess up the control flow of the code.
Perspectives:
I have the impression that GraphPlot is built around LightGraphs and MixedGraph() is not yet a method. But preparing for a graph tool, in the case of a future MixedGraph() method, could be nice either way.
What do you think?
Do you find any immediate issues or should I try to start making it work?
All the best,
Benjamin

Great idea. We basically need to support arrowlengthfrac to be a vector of reals, rather than a Real. Would you still be interested in taking a stab at it?
