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
Load wordcloud.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.
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.
