Using DViz.js with ActiveAdmin (Rails)

At https://BringBee.ch we have an internal ActiveAdmin App that we use to keep tabs on the recent activity. It's dashboard could do with some pretty graphs showing the stats of orders processed each week.

Today I ran across https://github.com/akngs/dviz so I decided to give it a spin. What follows is not by any means best practice but it got the results I wanted. The steps were pretty simple:

Get the source

in your vendor/assets/javascripts:

jopotts

module RandomString

  HUMAN = %w{2 3 4 6 7 9 a c d e f g h j k m n p q r t v w x y}
  LOWER = [*'a'..'z']
  PARAM = [*'a'..'z', *0..9]
  FULL  = [*'a'..'z', *'A'..'Z', *0..9]
  MIXED = [*'a'..'z', *'A'..'Z']

  def self.by_rand(length = 8, set = :full)
    chars = get_chars(set)
