Here is the simplest mediawiki extension you can write:

• in LocalSettings.php, add

include("extensions/circlextension.php");

• create a file extensions/circlextension.php:

<?php

$wgExtensionFunctions[] = "wfcirclextension";

function wfcirclextension()
{
  global $wgParser;
  $wgParser->setHook("circle", "circlehtml");
}

function circlehtml($code, $argv)
{
  $result="<svg><circle r=50 /></svg>";
  return $result;
}

• Now you can create a mediawiki page with the content

This is mediawiki-syntax
<circle "this goes into argv">
this goes into code
</circle>

• And you will see a circle on the resulting wiki page. Note the circle may not be complete.
