Excellent plugin.
After calling the plugin to render the tag cloud (because the spans are populated via ajax). There are some times that the canvas does not render the cloud, but the spans exists.
var settings = {
"shape": "square",
"options": {
"rotationRatio": "0.3",
"printMultiplier": 1
},
"color": {
"start": "#fff",
"end": "#fff"
},
"size": {
"grid": 8,
"factor": 18
}
};
$("#awesomeWordcloud").awesomeCloud(settings);
