[julia-users] Re: Coordinates of graph layout algorithms

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

Hello colleague, Tom Breloff maintains the Plots.jl (https://github.com/tbreloff/Plots.jl) package which is a meta-plotting thing (a layer above the actual plotting and rendering toolkits) and he collects some examples in https://github.com/tbreloff/ExamplePlots.jl, e.g.

Re: [julia-users] Re: Adding another function to Cairo.jl

It took me some iterations to get a PR and the git/github logic correctly (you might look into my old and closed PRs). I'd recommend (because i believe in testing) to do add an example along the implementation. And i want to turn around your comment: The thing about Cairo and Cairo.jl is —
