| <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> | |
| </p> | |
