<h2>Dynamic Data - Importing from Gephi (JSON)</h2>
<div style="width:700px; font-size:14px; text-align: justify;">
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.
<br/>
</div>
<p>
<label><input type="checkbox" id="allowedToMove"/> Allow to move after import.</label><br>
<label><input type="checkbox" id="parseColor"/> Parse the color instead of
copy (adds borders, highlights etc.)</label>
