Embedding in Google Sites

I have tried embedding my tag cloud (https://tagul.com/show/nphvuhfhsfgm/IPO) into google sites a variety of ways:

* Flash gadget [gigya src="http://cdn.tagul.com/cloud.swf" type="application/x-shockwave-flash" allowscriptaccess="always" width="number" height="number" flashvars="id=http://cdn.tagul.com/embed/flash/ik3j5x6qxeqd"]

* Google Embed Gadget [<div style="width: 400px; height: 400px; padding-bottom: 30px;">
<script src="http://cdn.tagul.com/embed/nphvuhfhsfgm"></script>
<!-- Please don't remove attribution to Tagul.com -->
<div style="display: table; margin: 0 auto;">Created with Tagul.com</div>
</div>]

* Iframe Gadget(I don't like this method, I want to embed the word cloud, not necessarily tagul.com)

* editing/pasting the code directly into the html editor (google strips the html code out).

I'm at my wits end and not sure how to proceed. Google searches aren't giving me any answers right now either. At this point I am not sure if the embed is even possible? I'd like to get this cloud operational on my site today can anyone help me please?

Make an html file:

Save it in a public Google Drive folder, get its URL and insert it into your site using an iframe gadget.
