I need to work with a graph where the vertices are tuples. All the graph libraries I’ve seen in Julia expect the graph vertices to be integers. Any suggestions?

You can use [MetaGraphs.jl](https://github.com/JuliaGraphs/MetaGraphs.jl) and keep tuples as vertices metadata or just keep external dict with necessary bindings.
