Accepted Solutions
Hey Lewis,
This should get you started. I have built something similar from scratch for an facebook/twitter app but this looks more promising and alot less effort to maintain.
For very large amounts of text I still would like to move the calculation of words out of the object into the QV engine instead since it's server side and much faster. In my loadscript I calculate the frequency of words and add counters instead. But that could easily be incorporated into this lib aswell.
As for an central repository it would be an awesome idea. We have an internal project for this but I guess GitHub, or something similar, would be better so external people would gain access.
Edit: I just checked your qvw and you did exactly what I proposed above, sorry about that 
As for the script.js:
//Declare variables for unique divIDs
var r=Math.floor(Math.random()*10001);
var divName = "div" + r;
//Changed load order. Makes more sense to load libs before init of the object fires.
Qva.LoadScript ("/QvAjaxZfc/QvsViewClient.aspx?public=only&name=Extensions/WordCloud/nebulos-min.js", function () {
Qva.AddExtension('WordCloud', function() {
//Check for existing objects so updates works
if (this.Element.children.length == 0) {
var ui = document.createElement("div");
ui.setAttribute("id",divName);
ui.setAttribute("style","width: 100%; height: 100%");
this.Element.appendChild(ui);
}
var vis = new metaaps.nebulos(ui);
// pass it a text string - Either a field with data or a result from an expression could go here
var myText = "in-memory analytics business discovery more corporate buzzwords then I can think off";
vis.draw(myText);
});
});
