The following screenshot is an example of a tag cloud generated by this plugin (with the help of OpenCloud that does all the tag clouding stuff):
The XHTML fragment looks like this:
<div class="tag-cloud"> <span style="font-size: 16px;">annotation</span> <span style="font-size: 16px;">buffer</span> <span style="font-size: 16px;">builder</span> <span style="font-size: 18px;">categories</span> <span style="font-size: 12px;">cause</span> <span style="font-size: 33px;">checkArguments</span> <span style="font-size: 16px;">column</span> <span style="font-size: 51px;">config</span> <span style="font-size: 12px;">document</span> <span style="font-size: 35px;">element</span> <span style="font-size: 21px;">ExecutableElement</span> <span style="font-size: 12px;">extractorConfig</span> <span style="font-size: 51px;">File</span> <span style="font-size: 18px;">hints</span> <span style="font-size: 12px;">ImageHelper</span> <span style="font-size: 19px;">index</span> <span style="font-size: 13px;">info</span> <span style="font-size: 17px;">InformationFilter</span> <span style="font-size: 16px;">input</span> <span style="font-size: 13px;">JUnitTestCaseDoc</span> <span style="font-size: 18px;">line</span> <span style="font-size: 13px;">LinkConstructorStrategyConfig</span> <span style="font-size: 33px;">List</span> <span style="font-size: 15px;">location</span> <span style="font-size: 17px;">Map</span> <span style="font-size: 19px;">message</span> <span style="font-size: 21px;">NAME</span> <span style="font-size: 35px;">Object</span> <span style="font-size: 16px;">output</span> <span style="font-size: 19px;">packageName</span> <span style="font-size: 39px;">ReportId</span> <span style="font-size: 19px;">result</span> <span style="font-size: 13px;">resultType</span> <span style="font-size: 16px;">rootDir</span> <span style="font-size: 12px;">scenarios</span> <span style="font-size: 18px;">ScenarioTestDoc</span> <span style="font-size: 12px;">SECTION</span> <span style="font-size: 15px;">SourceCodeHelper</span> <span style="font-size: 15px;">SourceCodeLocation</span> <span style="font-size: 12px;">testCase</span> <span style="font-size: 56px;">testCaseType</span> <span style="font-size: 39px;">testDoc</span> <span style="font-size: 19px;">testMethod</span> <span style="font-size: 19px;">testMethodDoc</span> <span style="font-size: 13px;">testName</span> <span style="font-size: 17px;">testNameUtils</span> <span style="font-size: 45px;">Type</span> <span style="font-size: 12px;">typeName</span> <span style="font-size: 44px;">UnitTestDoc</span> <span style="font-size: 18px;">UnitTestDocIndex</span> </div>
