Content

Most of what I know about Markov processes is from Jurafsky and Martin's NLP textbook:

Daniel Jurafsky and James H. Martin. 2000. Speech and Language Processing: An Introduction to Natural Language Processing, Computational Linguistics, and Speech Recognition (1st ed.). Prentice Hall PTR, Upper Saddle River, NJ, USA.

Libraries

• D3.js, "D3.js is a JavaScript library for manipulating documents based on data."
  • Implements the math/physics for the force layout, but none of the rendering.
  • Some convenience methods for manipulating data (e.g. color and linear scales)
  • Light abstraction around events (e.g. combining touch and click events)
• Lodash.js, "A JavaScript utility library delivering consistency, modularity, performance, & extras."
  • Used wherever you see the `_` function, fixes problems with JavaScripts collection methods. I primarily use it to make array/object methods chainable and to take a little more functional approach to writing loops.

Borrowed code/ideas

The Point object is modeled after Processing's PVector and Paper's Point.

The arrows at the tips of the quadratic curves used this guy on Stackoverflow's math.

Animating on Bezier curves (quadratic and cubic) uses De Casteljau's algorithm, as proposed by this guy on Stackoverflow. Also Pomax's interactive Bezier intro was very useful at helping me just wrap my mind around how Beziers work.

The efficiently delete all children of a given DOM node code I borrowed from Stackoverflow

This code lets you have variable length argument lists:

      vals = 1 <= arguments.length ? slice.call(arguments, 0) : [];

      // Somewhere later...
      app.some_function.apply(some_scope, vals);
      

Using `void 0` instead of `undefined` is a safer since it is a statement (that always returns undefined) and thus cannot be overwritten (undefined can). Discussion here

Scope management for your IFFEs:

      // IFFE with:
      (function() {}).call(this)
      // Instead of
      (function() {})()
