The STV_WordCloud plug-in reads an XML file to create wordcloud type visualizations. This plug-in allows users to read items from the DataHub that are compatible with the plug-in.

Note: This plug-in must be placed on top of a text geometry.

Examples are feeds from Dizplai World Cloud, Spredfast Top Terms, etc. The plug-in then visualizes the data in the form of a Word Cloud.

The plug-in is compatible with Dizplai’s XML format, but it can read any XML in the following structure:

<datasource>
<entry>
<field name="text">This</field>
<field name="count">967</field>
</entry>
<entry>
<field name="text">is</field>
<field name="count">772</field>
</entry>
<entry>
<field name="text">a</field>
<field name="count">150</field>
</entry>
<entry>
<field name="text">sample</field>
<field name="count">144</field>
</entry>
<entry>
<field name="text">XML</field>
<field name="count">119</field>
</entry>
<entry>
<field name="text">file</field>
<field name="count">106</field>
</entry>
</datasource>

Note: This plug-in is located in: Plugins -> Container plug-ins -> SocialTV
