jQuery.awesomeCloud v0.2 indyarmy.com

IndyArmy Network, Inc.

Usage:
    $( "#myContainer" ).awesomeCloud( settings );

    Your container must contain words in the following format:
        <element data-weight="12">Word</element>
    The <element> can be any valid HTML element (for example, <span>), and
    the weight must be a decimal or integer contained in the "data-weight"
    attribute. The content of the <element> is the word that will be
    displayed. The original element is removed from the page (but not the DOM).

Settings:
    "size" {
        "grid" : 8, // word spacing; smaller is more tightly packed but takes longer
        "factor" : 0, // font resizing factor; default "0" means automatically fill the container
        "normalize" : true // reduces outlier weights for a more attractive output
    },
    "color" {
        "background" : "rgba(255,255,255,0)", // default is transparent
        "start" : "#20f", // color of the smallest font
        "end" : "#e00" // color of the largest font
    },
    "options" {
        "color" : "gradient", // if set to "random-light" or "random-dark", color.start and color.end are ignored
        "rotationRatio" : 0.3, // 0 is all horizontal words, 1 is all vertical words
        "printMultiplier" : 1 // 1 will look best on screen and is fastest; setting to 3.5 gives nice 300dpi printer output but takes longer
    },
    "font" : "Futura, Helvetica, sans-serif", // font family, identical to CSS font-family attribute
    "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 ) {}

Notes:
    AwesomeCloud uses the HTML5 canvas element to create word clouds
    similar to http://wordle.net/. It may or may not work for you.

    If your words are all fairly evenly weighted and are large compared to
    the containing element, you may need to adjust the size.grid setting
    to make the output more attractive. Conversely, you can adjust the
    size.factor setting instead.

    It should be noted that the more words you have, the smaller the size.grid,
    and the larger the options.printMultiplier, the longer it will take to
    generate and display the word cloud.

Extra Thanks:
    Without Timothy Chien's work (https://github.com/timdream/wordcloud),
    this plugin would have taken much longer and been much uglier. Fate
    smiled and I found his version while I was searching out the equations
    I needed to make a circle-shaped cloud. I've simplified and, in places,
    dumbified his code for this plugin, and even outright copied chunks of
    it since those parts just worked far better than what I had originally
    written. Many thanks, Timothy, for saving some of my wits, sanity and
    hair over the past week.

    Thanks to http://www.websanova.com/tutorials/jquery/jquery-plugin-development-boilerplate
    for providing a great boilerplate I could use for my first jQuery plugin.
    My original layout worked, but this one was much better.
