preview and save svg

[kongdd]

In the following example, nothing was displayed, and no any output. Could you give some guide about how to preview and save svg?

using Karnak
using Graphs
using Colors
g = barabasi_albert(100, 1)
@drawsvg begin
    background("black")
    sethue("grey40")
    fontsize(8)
    drawgraph(g, 
        layout=stress, 
        vertexlabels = 1:nv(g),
        vertexfillcolors = 
            [RGB(rand()/2, rand()/2, rand()/2) 
               for i in 1:nv(g)]
    )
end 600 400
# Luxor drawing: (type = :svg, width = 600.0, height = 400.0, location = in memory)

Hi there! You're running in a terminal, which can't display any graphical output. When you run in an environment with graphical capabilities, the SVG source returned by @drawsvg will display in a Plots window or in the notebook environment itself. The text-only representation of a Luxor drawing is Luxor drawing: (type = :svg, width = 600.0, height = 400.0, location = in memory).

Karnak is built on Luxor, so for everything except the drawgraph() function and graphing features, you should refer to the little Luxor manual. The section on Creating Drawings is probably a useful source of information.

Happy reading!
