Cubist

Cubist is a Cubism graphing sandbox.

Enter Cube or Graphite expressions, get charts.

Charts are chucked in local storage for later use.

Features

server preferences and past expressions saved to local storage
comparison charts can be created by dragging one chart onto another (screenshot)

$ npm install -g cubist

$ cubist

Using port 3000 already? Fine.

$ export PORT=1234; cubist

correct any node/JS stupidity (I rarely touch node or frontend code; much to improve)
use Backbone or other framework to clean up JS
add support for managing lists of servers
live editing for existing charts
kill data polling when charts are removed
UI for removing old expressions
change typeahead into an autocomplete based on functions and metrics available
