Self loop nodes

[MaximeBouton]

Hello,
Is it possible to draw a node with a self loop? How would one proceed?

I tried the following:

using LightGraphs
g = SimpleDiGraph(2)
add_edge!(g, (2, 1))
add_edge!(g, (1,1))
TikzGraphs.plot(g, node_styles=Dict(1=>"loop below"))

The arrow corresponding to the edge (1,1) seems to be there but is poorly formatted.

Very close. It should look like this:

We might want to update the docs to illustrate this.

Thanks! I can submit a PR with this example
