The DataVisualizer extension lets you create graph-style visualizations from data in your wiki. It is also a library that could be used by other extensions like Semantic Results Formats to render visualizations.


DataVisualizer was originally written by Nischay Nahata, as WikiWorks consultant.


  • Download and place the file(s) in a directory called DataVisualizer in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    require_once "$IP/extensions/DataVisualizer/DataVisualizer.php";
  • YesY Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


The extension could be used as a tag or by other extensions to generate visuals

An example usage is

<dv_d3_tree name="Wikimedia Projects" size=5>name=Wikipedia|size=5,name=Wikidata|size=1,name=Wiktionary|size=2</dv_d3_tree>

The graphics will look like:
