Add example with WGLMakie

[tlienart]

Thanks to @SimonDanisch's hard work, it's now basically possible to export standalone javascript from a Makie plot (with the constraint that, at the moment, it doesn't support much interactivity if any).

Example provided by Simon in this issue

using JSServe, WGLMakie, AbstractPlotting

function handler(session, request)
    return scatter(1:4, color=1:4)
end

dir = joinpath(@__DIR__, "test")
mkdir(dir)
JSServe.export_standalone(handler, dir)
# Then serve it with e.g. LiveServer
using LiveServer

LiveServer.serve(dir=dir)

Could be adapted to be an example along PlotlyJS.

When running the code above, I currently get the following error, when running JSServe.export_standalone(handler, dir)

ERROR: MethodError: no method matching JSServe.UrlSerializer(::Bool, ::String, ::Bool, ::String

Closing as there's a demo of how to do this properly now: https://franklinjl.org/demos/#016_using_wglmakie_jsserve (https://franklinjl.org/demos/wgl/)

The example now errors, failing to precompile wglmakie https://franklinjl.org/demos/wgl/

Yeah WGLMakie is deprecated but thanks for flagging the issue.

This is now handled with Makie directly. Xranklin.jl (next version of Franklin, in prep) handles this. But generally, I'd probably suggest people use something else than Makie for their static site plots as it's still a bit flaky, and even when it works, it doesn't work on all browsers as webgl is not systematically on.
