<h2>Dynamic Data - Importing from Gephi (JSON)</h2>
|
|
<div style="width:700px; 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.

|
|
</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.)
