Vega.jl on METADATA works for version 0.6 in Jupyter Notebook. Work to convert to version 3 of Vega and adding support for Atom/Juno may happen in the future, but is not my highest priority. -- Randy, 1/10/2018
A Julia package for creating Vega visualizations. Convenience functions for common visualizations are provided, while also allowing for unlimited customization through modification of the main VegaVisualization composite type.
At a high-level, Vega.jl is designed to provide an easy-to-use library to quickly make common visualizations, while also including some of the interactivity provided as part of the Vega 2.x JavaScript library. This package also provides a declarative syntax that deviates from Grammar-of-Graphics style packages.
This package is unrelated to VegaLite.jl, other than to have the same underlying vega JavaScript engine. Perhaps that will change in the future as cross-package efficiencies become more obvious!

using Vega
Using Vega from the REPL/Atom will work with or without an Internet connection, as the required JavaScript libraries are injected into the HTML before the browser is opened (automatically).
Please see the documentation, which is rendered on-the-fly using Vega code generated from Vega.jl
GitHub issues has a To-Do list of visualizations and open bugs/feature requests; of course, any contribution is welcomed!
