1. Install system dependencies:

   sudo apt-get install build-essential curl g++ gcc python-dev
   

2. Install NVM and Node 8.x:

   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
   

3. Install Node dependencies:

   cd /path/to/plover
   npm install
   

4. Install R dependencies:

   install.packages(c("jsonlite", "purrr", "rmarkdown"))
   

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.

• Finch - Vega-Lite specification generator
• Vega-Lite: specifications
• Vega-Lite: theme configuration

• hrbrmstr/vegalite - Write Vega-Lite specs in R
• mdequeljoe/vl - Write Vega-Lite specs in R
• ijlyttle/altair - R interface to Altair (Python)
