Hello colleague, i touched the topic of a 'layout engine' a few times in various julia plotting discussions and would really like to see a package that deal with this, with an abstract interface and not tied to a special rendering step (different than d3.js). Graph layout would be a sub task of this. Actually Compose.jl is in some sense a layout engine of it's own, so at least there would be some parallel work.
I'd be in favour of a dedicated graph layout package and i'd recommend to start fresh and import working code from the available kits.
