- <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>
-
-
- <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.)
