I've done exactly this, rendering Venn diagrams using Google Charts from Solr.
See my presentation here:
<http://www.slideshare.net/erikhatcher/rapid-prototyping-with-solr-5675936>
See slides 26-29, even with full code in the slides, but the code is also
available here:
<https://github.com/erikhatcher/solr-rapid-prototyping/tree/master/ApacheCon2010>
And, yup, facet.query was leveraged for this.
