# The simplest thing that could possibly work. Will probably overwrite files if someone uploads
# a file that has the same file name as an already uploaded file. Requires the columns 'size' and
# 'content_type', see the 'store_file' method. You could obviously just remove those calls
# if you don't want to store the file size and the content type in the database.
#
# If you need a fancy name (in the spirit of 'paperclip' and 'attachment_fu'), you can call this code
# 'fucking_simple_fu' so that you can refer to this code and look like a cool kid on teh block.

# Grass.new takes two arguments: 1. a dataset consisting of an array of arrays:
#
#   [["Label", 10], ["Second label", 78]]
#
# the second argument is optional, and should be a hash of desired options:
#
#   :width      - specify a CSS width, e.g. '100px' or '70%'
#   :height     - specify a CSS height, e.g. '200px' or '60%'
#   :color      - color of the bars, e.g. '#224488'
#   :text_color - color of label when placed inside a bar, e.g. '#DDDDDD'
