- <h1>Network</h1>
-
- <p>Network is a visualization to display networks and networks consisting of nodes and edges. The visualization
- is easy to use and supports custom shapes, styles, colors, sizes, images, and more.
-
- The network visualization works smooth on any modern browser for up to a few thousand nodes and edges. To
- handle a larger amount of nodes, Network has clustering support. Network uses HTML canvas for rendering.</p>
-
- <p>As of 4.0, the network consists of individual modules which handle specific parts of the network. These modules
- have their own docs, options, methods and events which you can access
- by clicking on the modules in the list below.</p>
-
- <a class="btn btn-primary" role="button" onclick="toggleGettingStarted(this)">Show the getting started!</a>

- <h3>Creating a Network</h3>
-
- <p>
- Creating a vis network is easy. <a href="http://visjs.org/#download_install" target="_blank">It requires you to
- include the vis.js and css files which you can get here</a>. If you have these
- added to your application, you will need to specify your nodes and edges. You can use DOT language or export
- nodes and edges from Gephi if you'd like but we will do it without these for now.
- For more information on this click the tabs below. You can also use the vis.DataSets for dynamic data binding,
- for instance, changing the color, label or any option after you have initialized the network.
- <br><br>
- Once you have the data, all you need is a container div to tell vis where to put your network. Additionally you
- can use an options object to customize many aspects of the network. In code this
- looks like this:</p>
-

- {id: 4, label: 'Node 4'},

- Network supports data in the
- <a href="http://en.wikipedia.org/wiki/DOT_language" target="_blank">DOT language</a>.
- To use data in the DOT language, you can use the vis.network.convertDot converter to transform the DOT
- language
- into a vis.Network compatible nodes, edges and options objects. You can extend the options object with other
- options if you'd like.
- </p>
-
- <p>
- Example usage:
- </p>
-
- <pre class="prettyprint lang-js">
- // provide data in the DOT language
- var DOTstring = 'dinetwork {1 -> 1 -> 2; 2 -> 3; 2 -- 4; 2 -> 1 }';
- var parsedData = vis.network.convertDot(DOTstring);
-
- var data = {
- nodes: parsedData.nodes,
- edges: parsedData.edges
- }
-
- var options = parsedData.options;
-
- // you can extend the options like a normal JSON variable:
- options.nodes = {
- color: 'red'
- }
-
- // create a network
- var network = new vis.Network(container, data, options);
- </pre>
- </div>
- <div id="gephiDiv" class=" hidden">
- <p>
- Network can import data straight from an exported json file from gephi. You can get the JSON exporter here:
- <a href="https://marketplace.gephi.org/plugin/json-exporter/" target="_blank">https://marketplace.gephi.org/plugin/json-exporter/</a>.
- An example exists showing how to get a JSON file into Vis: <a
- href="../examples/network/30_importing_from_gephi.html">30_importing_from_gephi</a>.
- </p>
-
- <p>
- Example usage:
- </p>
-
- <pre class="prettyprint lang-js">
- // load the JSON file containing the Gephi network.
- var gephiJSON = loadJSON("./data/WorldCup2014.json"); // code in example 30
-
- // you can customize the result like with these options. These are explained below.
- // These are the default options.
- var parserOptions = {
- edges: {
- inheritColors: false
- },
- nodes: {
- fixed: true,
- parseColor: false
- }
- }
-
- // parse the gephi file to receive an object
- // containing nodes and edges in vis format.
- var parsed = vis.network.convertGephi(gephiJSON, parserOptions);
-
- // provide data in the normal fashion
- var data = {
- nodes: parsed.nodes,
- edged: parsed.edges
- };
-
- // create a network
- var network = new vis.Network(container, data);

- <h4>Gephi parser options</h4>
-
- There are a few options you can use to tell Vis what to do with the data from Gephi.
- <table class="moduleTable">
- <tr class="header">
- <td>name</td>
- <td>type</td>
- <td>default</td>
- <td>description</td>
- </tr>
- <tr>
- <td>nodes.fixed</td>
- <td class="mid">Boolean</td>
- <td class="mid"><code>true</code></td>
- <td>When false, the nodes will move according to the physics model after import. If true, the nodes do
- not move at all. If set to true, the node positions have to be defined to avoid infinite recursion
- errors in the physics.
- </td>
- </tr>
- <tr>
- <td>nodes.parseColor</td>
- <td class="mid">Boolean</td>
- <td class="mid"><code>false</code></td>
- <td>If true, the color will be parsed by the vis parser, generating extra colors for the borders,
- highlighs and hover. If false, the node will be the supplied color.
- </td>
- </tr>
- <tr>
- <td>edges.inheritColor</td>
- <td class="mid">Boolean</td>
- <td class="mid"><code>false</code></td>
- <td>When true, the color supplied by gephi is ignored and the inherit color mode is used with the global
- setting.
