-Internally, shiny and htmlwidgets use the R package [jsonlite](https://cran.r-project.org/web/packages/jsonlite/index.html) to convert R data structures to JSON. For more information about jsonlite, take a look at the package [vignette](https://cran.r-project.org/web/packages/jsonlite/vignettes/json-aaquickstart.html). Especially useful are the `fromJSON` and `toJSON` functions. The first tells you how an R object will be translated into JSON, while the latter does the reverse. Just play around to see how it works!
