HTML5 Word Cloud

Word Cloud on HTML5 canvas, inspired by Wordle.

Author: Timothy Chien <timdream@gmail.com>

Intro

HTML5 Word Cloud is inspired by Wrodle, instead of generate the image on a Java Applet, this experiment is entirely on HTML5 canvas.

This program is composed of three libraries, two of them have dependency of jQuery thus they are warped as jQuery plug-ins:

jquery.getcontent.js which access remote or local content though Google Feed API, YQL data.html (experimental), Facebook Javascript SDK, and FileReader API.
wordfreq.js which count the phrases/words by running N-gram analysis (for Chinese) and Porter Stemming Algorithm (for English) in Web Workers.
finally, jquery.wordcloud.js draw the phrases/words on canvas using configured parameters.

Each of the libraries comes with their own tests/demos and are designed to be reusable.

Following external libraries are included:

Porter Stemming Algorithm in Javascript as mentioned above.
Simulated Web Workers (worker.js) to provide a simulated web workers interface in IEs and Mobile Safari.
