An example exists showing how to get a JSON file into Vis: <ahref="../examples/Network/30_importing_from_gephi.html">30_importing_from_gephi</a>.
</p>
<p>
Example usage:
</p>
<preclass="prettyprint lang-js">
// load the JSON file containing the Gephi network.
var gephiJSON = loadJSON("./data/WorldCup2014.json"); // code in example 30
// create a data object with the gephi key:
var data = {
gephi: gephiJSON
};
// create a network
var network = new vis.Network(container, data);
</pre>
Alternatively you can use the parser manually:
<preclass="prettyprint lang-js">
// load the JSON file containing the Gephi network.
var gephiJSON = loadJSON("./data/WorldCup2014.json"); // code in example 30
// parse the gephi file to receive an object
// containing nodes and edges in vis format.
var parsed = vis.network.gephiParser.parseGephi(gephiJSON);
// provide data in the normal fashion
var data = {
nodes: parsed.nodes,
edged: parsed.edges
};
// create a network
var network = new vis.Network(container, data);
</pre>
<h4>Gephi parser options</h4>
There are a few options you can use to tell Vis what to do with the data from Gephi.
<preclass="prettyprint lang-js">
var parserOptions = {
allowedToMove: false,
parseColor: false
}
var parsed = vis.network.gephiParser.parseGephi(gephiJSON, parserOptions);
</pre>
<table>
<tr>
<th>Name</th>
<th>Type</th>
<th>Default</th>
<th>Description</th>
</tr>
<tr>
<td>allowedToMove</td>
<td>Boolean</td>
<td>false</td>
<td>
If true, the nodes will move according to the physics model after import. If false, the nodes do not move at all.
</td>
</tr>
<tr>
<td>parseColor</td>
<td>Boolean</td>
<td>false</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.
This example shows the power of the DataSet. Once a node is clicked, all nodes are greyed out except for the first and second order connected nodes.

This example shows how to import a JSON file exported by Gephi. The two options available for the import are
available through the checkboxes. You can download the Gephi JSON exporter here:
