Finally , I have convert the jqcloud div to svg element.

var UNDEFINED,SVG_NS = ‘http://www.w3.org/2000/svg’;

/**
* Returns true if the object is not null or undefined.
* @param {Object} obj
*/
function defined(obj) {
return obj !== UNDEFINED && obj !== null;
}

/**
* Set or get an attribute or an object of attributes. Can’t use jQuery attr because
* it attempts to set expando properties on the SVG element, which is not allowed.
*
* @param {Object} el The DOM element to receive the attribute(s)
* @param {String|Object} prop The property or an abject of key-value pairs
* @param {String} value The value if single property is set
*/
function attribute(el, prop, value)
{
var result=null;
if (typeof(prop)===’string’) {
if (defined(value)) {
el.setAttribute(prop, value);
}
else if (el && el.getAttribute) {
result = el.getAttribute(prop);
}

} else if (defined(prop) && typeof(prop)===’object’) { //key/value pairs
var key;
for (key in prop) {
el.setAttribute(key, prop[key]);
}
}
return result;
}

/**
* get all basic styles (‘font-family’,'font-size’,'color’) from a DOM element
*
* @param {Object} el The DOM element from get the styles
*
*/
function getAllStyles(el)
{
var styles =['font-family','font-size','color'];
var svgStyles =["font-family","font-size","fill"];
var len = styles.length, style=”;
for (var i = 0; i < len; i++)
{
style=style+svgStyles[i]+':'+ jQuery(el).css(styles[i])+';';
}
return style;
}

/**
* Parse a Jqcloud div into SVG element
*
* @param {String} div_id the id of the Jqcloud div
*/

function jqCloudToSVG(div_id) {
var svg=document.createElementNS(SVG_NS,"svg");
attribute(svg,{xmlns:SVG_NS,version:'1.1',width:jQuery('#'+div_id).width(),height:jQuery('#'+div_id).height()});
jQuery('#'+div_id+' span').each(function(index, span){
var word=jQuery(span).text(),
style=getAllStyles(span),
svgText =document.createElementNS(SVG_NS,'text'),
tspan= document.createElementNS(SVG_NS,'tspan');

attribute(svgText,'x',parseInt(jQuery(span).css('left'),10));
attribute(svgText,'y',parseInt(jQuery(span).css('top'),10));
attribute(svgText,'style',style);
tspan.appendChild(document.createTextNode(word));

var lineHeight=(parseInt(jQuery(span).css('font-size'),10));

attribute(tspan,'dy',lineHeight);

svgText.appendChild(tspan);
svg.appendChild(svgText);
});
var svgJQcloud=document.createElement('div');
jQuery(svgJQcloud).append(svg);
return svgJQcloud;
}

I didn't cover all features.
