Magic Console is a package for Atom that evaluates code in pretty much any language and renders the output alongside the source code. If that alone weren't good enough, it also visualizes the outputs in a human-friendly way (e.g. string as Markdown, array as table, object/dictionary as tree). Wait there's more! Visualizations are entirely pluggable, so you can take advantage of the core plugins and plugins created by the community or create a custom plugin for your specific application. Use Magic Console to try out code, explore results, run experiments, etc.
