+ <h1>Graph3d</h1>
+
+ <h2 id="Overview">Overview</h2>
+ <p>
+ Graph3d is an interactive visualization chart to draw data in a three dimensional
+ graph. You can freely move and zoom in the graph by dragging and scrolling in the
+ window. Graph3d also supports animation of a graph.
+ </p>
+ <p>
+ Graph3d uses <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Canvas">HTML canvas</a>
+ to render graphs, and can render up to a few thousands of data points smoothly.

+ The class name of the Graph3d is <code>vis.Graph3d</code>.
+ When constructing a Graph3d, an HTML DOM container must be provided to attach
+ the graph to. Optionally, data an options can be provided.
+ Data is a vis <code>DataSet</code> or an <code>Array</code>, described in
+ section <a href="#Data_Format">Data Format</a>.
+ Options is a name-value map in the JSON format. The available options
+ are described in section <a href="#Configuration_Options">Configuration Options</a>.

+ <pre class="prettyprint lang-js">var graph = new vis.Graph3d(container [, data] [, options]);</pre>

+ Data and options can be set or changed later on using the functions
+ <code>Graph3d.setData(data)</code> and <code>Graph3d.setOptions(options)</code>.
+ </p>
+
+ <h2 id="Data_Format">Data Format</h2>
+ <p>
+ Graph3d can load data from an <code>Array</code>, a <code>DataSet</code> (offering 2 way data binding), or a <code>DataView</code> (offering 1 way data binding).
+ JSON objects are added to this DataSet by using the <code>add()</code> function.
+ Data points must have properties <code>x</code>, <code>y</code>, and <code>z</code>,
+ and can optionally have a property <code>style</code> and <code>filter</code>.

+ <h3>Definition</h3>

+ Parameter <code>horizontal</code> is a value in radians and can have any
+ value (but normally in the range of 0 and 2*Pi).
+ Parameter <code>vertical</code> is a value in radians between 0 and 0.5*Pi.
+ Parameter <code>distance</code> is the (normalized) distance from the
+ camera to the center of the graph, in the range of 0.71 to 5.0. A
+ larger distance puts the graph further away, making it smaller.
+ All parameters are optional.

+ Graph3d fires events after the camera position has been changed.
+ The event can be catched by creating a listener.
+ Here an example on how to catch a <code>cameraPositionChange</code> event.
+ </p>

+function onCameraPositionChange(event) {
+ alert('The camera position changed to:\n' +
+ 'Horizontal: ' + event.horizontal + '\n' +

+graph3d.on('cameraPositionChange', onCameraPositionChange);
