<h2>Dynamic Data - Importing from Gephi (JSON)</h2>
|
|
<div style="width:900px; font-size:14px;">
|
|
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:
|
|
<a href="https://marketplace.gephi.org/plugin/json-exporter/" target="_blank">https://marketplace.gephi.org/plugin/json-exporter/</a>.
|
|
All of Gephi's attributes are also contained within the node elements. This means you can access all of this data through the DataSet. An example of this is shown next to the network.
|
|
<br /><br />
|
|
</div>
|
|
|
|
|
|
<input type="checkbox" id="allowedToMove">: Allow to move after import. <br/>
|
|
<input type="checkbox" id="parseColor">: Parse the color instead of copy (adds borders, highlights etc.)
