Track config visualizer for exercism.io

This is a simple Shiny app for visualizing the config.json files of language tracks on exercism.io.

It utilizes jsonlite to parse the JSON files and the visNetwork package for visualizing the progression of exercises as a network path.

It should be accessable via Shinyapps.io, provided that I haven't reached my usage quota.

Setup/Install

To run it locally, clone this repo and make sure you have installed R and RStudio as well as the following R packages:

install.packages("shiny")
install.packages("jsonlite")
install.packages("dplyr")
install.packages("visNetwork")
install.packages("shinycssloaders")

Then simply open up the project/directory in RStudio and run shiny::runApp().

Please feel free to open an issue or pull request if you encounter problems or would like to contribute fixes/improvements etc.
