#About

This is a simple scraper to dot file generator that parses MIT's Mathematics (Course 18) pages and generates a directed graph in math.dot and math.png. It could be used for other courses.

Example:

Usage:

$ bundle install
$ ruby course.rb 
[#<MITCourse:0x00000002c3fe68
  @name="Complex Variables with Applications",
  @number="18.04",
  @prerequisites=
   ["18.02", "18.02A", "18.022", "18.023", "18.024", "18.03", "18.034"]>]
Warning: dot does not support the aspect attribute for disconnected graphs or graphs with clusters

Motivation: If you hear about an interesting subject, it's helpful to know the general prerequisites for it. This is top-down course planning instead of bottom up. It's always helpful to ask your advisor, but this visualization can help you get an idea of the right questions to ask beforehand. It gives you the big picture.
