6Usage:
7    $( "#myContainer" ).awesomeCloud( settings );
8
9    Your container must contain words in the following format:
10        <element data-weight="12">Word</element>
11    The <element> can be any valid HTML element (for example, <span>), and
12    the weight must be a decimal or integer contained in the "data-weight"
13    attribute. The content of the <element> is the word that will be
14    displayed. The original element is removed from the page (but not the DOM).
15
16Settings:
17    "size" {
18        "grid" : 8, // word spacing; smaller is more tightly packed but takes longer
19        "factor" : 0, // font resizing factor; default "0" means automatically fill the container
20        "normalize" : true // reduces outlier weights for a more attractive output
21    },
22    "color" {
23        "background" : "rgba(255,255,255,0)", // default is transparent
24        "start" : "#20f", // color of the smallest font
25        "end" : "#e00" // color of the largest font
26    },
27    "options" {
28        "color" : "gradient", // if set to "random-light" or "random-dark", color.start and color.end are ignored
29        "rotationRatio" : 0.3, // 0 is all horizontal words, 1 is all vertical words
30        "printMultiplier" : 1 // 1 will look best on screen and is fastest; setting to 3.5 gives nice 300dpi printer output but takes longer
31    },
32    "font" : "Futura, Helvetica, sans-serif", // font family, identical to CSS font-family attribute
33    "shape" : "circle", // one of "circle", "square", "diamond", "triangle", "triangle-forward", "x", "pentagon" or "star"; this can also be a function with the following prototype - function( theta ) {}

35Notes:
36    AwesomeCloud uses the HTML5 canvas element to create word clouds
37    similar to http://wordle.net/. It may or may not work for you.
38
39    If your words are all fairly evenly weighted and are large compared to
40    the containing element, you may need to adjust the size.grid setting
41    to make the output more attractive. Conversely, you can adjust the
42    size.factor setting instead.
43
44    It should be noted that the more words you have, the smaller the size.grid,
45    and the larger the options.printMultiplier, the longer it will take to
46    generate and display the word cloud.

48Extra Thanks:
49    Without Timothy Chien's work (https://github.com/timdream/wordcloud),
50    this plugin would have taken much longer and been much uglier. Fate
51    smiled and I found his version while I was searching out the equations
52    I needed to make a circle-shaped cloud. I've simplified and, in places,
53    dumbified his code for this plugin, and even outright copied chunks of
54    it since those parts just worked far better than what I had originally
55    written. Many thanks, Timothy, for saving some of my wits, sanity and
56    hair over the past week.
57
58    Thanks to http://www.websanova.com/tutorials/jquery/jquery-plugin-development-boilerplate
59    for providing a great boilerplate I could use for my first jQuery plugin.
60    My original layout worked, but this one was much better.
