Create a tag cloud/Wordle presentation on 2D canvas or HTML.
This library is a spin-off project from HTML5 Word Cloud.
Visit the demo page
npm install wordcloud
Download the latest wordcloud2.js file from the src folder in this repository.
Load wordcloud2.js script to the web page, and run:
WordCloud(document.getElementById('my_canvas'), { list: list } );
where list is an array that look like this: [['foo', 12], ['bar', 6]].
Options available, see API documentation for detail.
Please read through the API documentation and CONTRIBUTING.md before filing an issue or contact me via e-mail.
Before putting each word on the canvas, it is drawn on a separate canvas to read back the pixels to record is drawn spaces. With the information, wordcloud.js will then try to find a place to fit the word that is closest to the start point.
Tests are available with QUnit and grunt.
To setup environment for testing, run npm install and manually install SlimerJS of your platform.
Use grunt test to ensure all options can be set without JavaScript error.
Use grunt compare --base-commit=gh-pages to compare your proposed fix with gh-pages branch.
The developer would like to thank Chad Jensen for sponsoring the work on image masking on the demo page.
