   curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash
   source ~/.bashrc
   nvm install v8.9.4
   nvm alias default v8.9.4

Usage

To get started, open /vega/index.Rmd in RStudio.

A Vega-Lite spec can be supplied in long-form, or generated with Finch, as done in this example.

A global theme is stored in /vega/theme.json. Remember to knit the document after making changes.
