Hi all,
I have found the Graphs.jl package difficult to work with, so I've been
(slowly) putting together a SimpleGraphs.jl package available
here: https://github.com/scheinerman/SimpleGraphs.jl
It's probably not as full featured as the Graphs.jl package, but it's
easier (at least for me) to use.
Please note that it is a work in progress, but I welcome contributions.
