Introduction to Karnak

Karnak.jl is a small extension for the Luxor.jl package to help with visualizing graphs and networks.

Karnak also relies on Graphs.jl for graph construction, and on NetworkLayout.jl for graph layout.

Note

There's a good selection of Julia packages for visualizing graphs:

TikzGraphs.jl: backend: Tikz/LaTeX
GraphPlot.jl: backend: Compose.jl
SGtSNEpi.jl: backend: Makie.jl
GraphRecipes.jl: backend: Plots.jl
GraphMakie.jl: backend: Makie.jl

Quick start

using Karnak
using Graphs
using NetworkLayout
g = barabasi_albert(100, 1)
@drawsvg begin
    background("black")
    sethue("white")
    drawgraph(g, layout=stress, vertexlabels = 1:nv(g))
end

Note

Karnak.jl contains just one function: drawgraph(), and re-exports Luxor.jl. So all graphics and drawing functions are from Luxor. See the documentation of Luxor.jl for details.
