jQuery.textCloud

Arranges a set of texts in a cloud using randomized placement. Note that not all texts are added, the algorithm skips texts when it cant find a place for them.

Repo

https://github.com/jwagner/jquery.textCloud/blob/master/jquery.textCloud.js

Usage

var terms = [
{text: 'Hello', scale: 1.0}, {text: 'World', scale: 1.2}

], options = {

colors: '#833 #444 #955 #666 #777 #888 #975'.split(' '), iterations: 100

};

$('#cloud').textCloud(terms, options);

CSS

While not strictly required it makes sense to style the items to get some nice CSS3 transitions.

.textCloud-item {

max-width: 10em; text-overflow: ellipsis; overflow: hidden; white-space: nowrap;

padding: 0.2em;

transition: left 1s ease-in-out; -moz-transition: left 1s ease-in-out; -webkit-transition: all 1s ease-in-out; -ms-transition: all 1s ease-in-out; -o-transition: all 1s ease-in-out;

}

Algorithm

for term in terms:
do
pick random position

while collision with already added term

add term
