The julia package VegaLite has just been added to the official repo (
install with Pkg.add("VegaLite") ). As the name suggests it provides
bindings to the VegaLite plotting library (yet another way to make graphs
with Julia !). VegaLite is a simplified version of Vega which reduces the
functionality but provides in turn a simpler way to define graphs (see
https://vega.github.io/vega-lite/).
VegaLite uses graph descriptions in JSON but the julia syntax proposed by
the package looks more like the ggplot syntax where a series of functions
builds up the graph specs. You can check out the Quick tour/presentation at
https://github.com/fredo-dedup/VegaLite.jl
The supported backends are the standard REPL (a browser window will open),
Escher and Jupyter.
Issues, enhancements proposals are of course welcome !
