<h2><a name="Overview"></a>Overview</h2>
<p>
Graph is a visualization to display graphs and networks consisting of nodes
and edges. The visualization is easy to use and supports custom styles,
colors, sizes, images, and more.
</p>
<p>
The graph visualization works smooth on any modern browser for up to a
few hundred nodes and edges.
</p>
<p>
To get started with Graph, install or download the
<a href="http://visjs.org" target="_blank">vis.js</a> library.
</p>
<h2><a name="Example"></a>Example</h2>
<p>
Here a basic graph example. More examples can be found in the
<a href="../examples" target="_blank">examples directory</a>.
</p>
<pre class="prettyprint lang-html">&lt;!doctype html&gt;
&lt;html&gt;
&lt;head&gt;
&lt;title&gt;Graph | Basic usage&lt;/title&gt;
&lt;script type="text/javascript" src="../../vis.js"&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;div id="mygraph"&gt;&lt;/div&gt;
&lt;script type="text/javascript"&gt;
// create an array with nodes
var nodes = [
{id: 1, text: 'Node 1'},
{id: 2, text: 'Node 2'},
{id: 3, text: 'Node 3'},
{id: 4, text: 'Node 4'},
{id: 5, text: 'Node 5'}
];
// create an array with edges
var edges = [
{from: 1, to: 2},
{from: 1, to: 3},
{from: 2, to: 4},
{from: 2, to: 5}
];
// create a graph
var container = document.getElementById('mygraph');
var data= {
nodes: nodes,
edges: edges,
};
var options = {
width: '400px',
height: '400px'
};
var graph = new vis.Graph(container, data, options);
&lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;
</pre>
<h2><a name="Loading"></a>Loading</h2>
<p>
Install or download the <a href="http://visjs.org" target="_blank">vis.js</a> library.
in a subfolder of your project. Include the library script in the head of your html code:
</p>
<pre class="prettyprint lang-html">
&lt;script type="text/javascript" src="vis/vis.js"&gt;&lt;/script&gt;
</pre>
The constructor of the Graph is <code>vis.Graph</code>.
<pre class="prettyprint lang-js">var graph = new vis.Graph(container, data, options);</pre>
The constructor accepts three parameters:
<ul>
<li>
<code>container</code> is the DOM element in which to create the graph.
</li>
<li>
<code>data</code> is an Object containing properties <code>nodes</code> and
<code>edges</code>, which both contain an array with objects.
Optionally, data may contain an <code>options</code> object.
The parameter <code>data</code> is optional, data can also be set using
the method <code>setData</code>.
</li>
<li>
<code>options</code> is an optional Object containing a name-value map
with options. Options can also be set using the method
<code>setOptions</code>.
</li>
</ul>
<h2><a name="Data_Format"></a>Data Format</h2>
<p>
The Graph draws nodes and edges, which are both an Array with objects.
This section describes the data format of nodes and edges.
</p>
<h3>Nodes</h3>
<p>
Nodes typically have an <code>id</code> and <code>text</code>.
A node must contain at least a property <code>id</code>.
Nodes can have extra properties, used to define the type and style the
nodes.
</p>
<p>
A JavaScript Array with nodes is constructed like:
</p>
<pre class="prettyprint lang-js">
var nodes = [
{
'id': 1,
'text': 'Node 1'
},
// ... more nodes
];
</pre>
<p>
Nodes support the following properties:
</p>
<table>
<tr>
<th>Name</th>
<th>Type</th>
<th>Required</th>
<th>Description</th>
</tr>
<tr>
<td>backgroundColor</td>
<td>String</td>
<td>"#97C2FC"</td>
<td>Background color for the node.</td>
</tr>
<tr>
<td>borderColor</td>
<td>String</td>
<td>"#2B7CE9"</td>
<td>Border color for the node.</td>
</tr>
<tr>
<td>group</td>
<td>*</td>
<td>no</td>
<td>A group number or name. The type can be <code>number</code>,
<code>string</code>, or an other type. All nodes with the same group get
the same color schema.</td>
</tr>
<tr>
<td>fontColor</td>
<td>String</td>
<td>"black"</td>
<td>Font color for text in the node.</td>
</tr>
<tr>
<td>fontFace</td>
<td>String</td>
<td>"sans"</td>
<td>Font face for text in the node, for example "verdana" or "arial".</td>
</tr>
<tr>
<td>fontSize</td>
<td>Number</td>
<td>14</td>
<td>Font size in pixels for text in the node.</td>
</tr>
<tr>
<td>highlightColor</td>
<td>String</td>
<td>"#D2E5FF"</td>
<td>Background color of the node when selected.</td>
</tr>
<tr>
<td>id</td>
<td>*</td>
<td>yes</td>
<td>A unique id for this node.
Nodes may not have duplicate id's.
Id's do not need to be consecutive.
An id is normally a number, but may be any type.</td>
</tr>
<tr>
<td>image</td>
<td>string</td>
<td>no</td>
<td>Url of an image. Only applicable when the style of the node is
<code>image</code>.</td>
</tr>
<tr>
<td>radius</td>
<td>number</td>
<td>no</td>
<td>Radius for the node. Applicable for all styles except <code>rect</code>,
<code>circle</code>, and <code>database</code>.
The value of <code>radius</code> will override a value in
property <code>value</code>.</td>
</tr>
<tr>
<td>style</td>
<td>string</td>
<td>no</td>
<td>Define the shape for the node.
Choose from <code>rect</code> (default), <code>circle</code>,
<code>database</code>, <code>image</code>, <code>text</code>,
<code>dot</code>, <code>star</code>, <code>triangle</code>,
<code>triangleDown</code>, and <code>square</code>.
<br><br>
In case of <code>image</code>, a property with name <code>image</code> must
be provided, containing image urls.
<br><br>
The shapes <code>dot</code>, <code>star</code>, <code>triangle</code>,
<code>triangleDown</code>, and <code>square</code>, are scalable.
The size is determined by the properties <code>radius</code> or
<code>value</code>.
<br><br>
When a property <code>text</code> is provided,
this text will be displayed inside the shape in case of styles
<code>rect</code>, <code>circle</code>, and <code>database</code>.
For all other shapes, the text will be displayed right below the shape.
</td>
</tr>
<tr>
<td>text</td>
<td>string</td>
<td>no</td>
<td>Text to be displayed in the node or under the image of the node.
Multiple lines can be separated by a newline character <code>\n</code> .</td>
</tr>
<tr>

<td>string</td>
<td>no</td>
<td>Title to be displayed when the user hovers over the node.
The title can contain HTML code.</td>
</tr>
<tr>
<td>value</td>
<td>number</td>
<td>no</td>
<td>A value for the node.
The radius of the nodes will be scaled automatically from minimum to
maximum value.
Only applicable when the style of the node is <code>dot</code>.
If a <code>radius</code> is provided for the node too, it will override the
radius calculated from the value.</td>
</tr>
<tr>
<td>x</td>
<td>number</td>
<td>no</td>
<td>Horizontal position in pixels.
The horizontal position of the node will be fixed.
The vertical position y may remain undefined.</td>
</tr>
<tr>
<td>y</td>
<td>number</td>
<td>no</td>
<td>Vertical position in pixels.
The vertical position of the node will be fixed.
The horizontal position x may remain undefined.</td>
</tr>
</table>
<h3>Edges</h3>
<p>
Edges are connections between nodes.
An edge must at least contain properties <code>from</code> and
<code>to</code>, both referring to the <code>id</code> of a node.
Edges can have extra properties, used to define the type and style.
</p>
<p>
A JavaScript Array with edges is constructed as:
</p>
<pre class="prettyprint lang-js">
var edges = [
{
'from': 1,
'to': 3
},
// ... more edges
];
</pre>
<p>
Edges support the following properties:
</p>
