+      alert("computed!");
+    }
+  });
+  (end code)
+  
+  Parameters:
+
+   onBeforeCompute(node) - This method is called right before performing all computations and animations. The selected <Graph.Node> is passed as parameter.
+   onAfterCompute() - This method is triggered after all animations or computations ended.
+   onCreateLabel(domElement, node) - This method receives a new label DIV element as first parameter, and the corresponding <Graph.Node> as second parameter. This method will only be called once for each label. This method is useful when adding events or styles to the labels used by the JIT.
+   onPlaceLabel(domElement, node) - This method receives a label DIV element as first parameter and the corresponding <Graph.Node> as second parameter. This method is called each time a label has been placed in the visualization, for example at each step of an animation, and thus it allows you to update the labels properties, such as size or position. Note that onPlaceLabel will be triggered after updating the labels positions. That means that, for example, the left and top css properties are already updated to match the nodes positions. Width and height properties are not set however.
+   onBeforePlotNode(node) - This method is triggered right before plotting each <Graph.Node>. This method is useful for changing a node style right before plotting it.
+   onAfterPlotNode(node) - This method is triggered right after plotting each <Graph.Node>.
+   onBeforePlotLine(adj) - This method is triggered right before plotting a <Graph.Adjacence>. This method is useful for adding some styles to a particular edge before being plotted.
+   onAfterPlotLine(adj) - This method is triggered right after plotting a <Graph.Adjacence>.
+
+    *Used in <ST>, <TM.Base> and <Icicle> visualizations*
+    
+    request(nodeId, level, onComplete) - This method is used for buffering information into the visualization. When clicking on an empty node, the visualization will make a request for this node's subtrees, specifying a given level for this subtree (defined by _levelsToShow_). Once the request is completed, the onComplete callback should be called with the given result. This is useful to provide on-demand information into the visualizations withought having to load the entire information from start. The parameters used by this method are _nodeId_, which is the id of the root of the subtree to request, _level_ which is the depth of the subtree to be requested (0 would mean just the root node). _onComplete_ is an object having the callback method _onComplete.onComplete(json)_ that should be called once the json has been retrieved.

+ Class: Canvas
+ 
+ 	A canvas widget used by all visualizations. The canvas object can be accessed by doing *viz.canvas*. If you want to 
+ 	know more about <Canvas> options take a look at <Options.Canvas>.
+ 
+ A canvas widget is a set of DOM elements that wrap the native canvas DOM Element providing a consistent API and behavior 
+ across all browsers. It can also include Elements to add DOM (SVG or HTML) label support to all visualizations.
+ 
+ Example:
+ 
+ Suppose we have this HTML
+ 
+ (start code xml)
+ 	<div id="infovis"></div>
+ (end code)
+ 
+ Now we create a new Visualization
+ 
+ (start code js)
+ 	var viz = new $jit.Viz({
+ 		//Where to inject the canvas. Any div container will do.
+ 		'injectInto':'infovis',
+		 //width and height for canvas. 
+		 //Default's to the container offsetWidth and Height.
+		 'width': 900,
+		 'height':500
+	 });
+ (end code)
+
+ The generated HTML will look like this
+ 
+ (start code xml)
+ <div id="infovis">
+ 	<div id="infovis-canvaswidget" style="position:relative;">
+ 	<canvas id="infovis-canvas" width=900 height=500
+ 	style="position:absolute; top:0; left:0; width:900px; height:500px;" />
+ 	<div id="infovis-label"
+ 	style="overflow:visible; position:absolute; top:0; left:0; width:900px; height:0px">
+ 	</div>
+ 	</div>
+ </div>
+ (end code)
+ 
+ As you can see, the generated HTML consists of a canvas DOM Element of id *infovis-canvas* and a div label container
+ of id *infovis-label*, wrapped in a main div container of id *infovis-canvaswidget*.
