This script is mainly for personal preference. Some people can often take preference in the viewing of their feedback. I think as members of deviantART, we all know how it feels not to get the kind of feedback we want- whether we prefer the "OMG, YOUR ART IS SO COOL!" comment or the long, drawn out critique.
When viewing poll data, I prefer looking at something fun and this script certainly provides that.
The only problem I've noticed is that in some cases, the text denoting the top left slice can often overlap the graph when the text is about a sentence or so (as can be seen in the creator's preview example).
Otherwise, a great script! One that I shall continue using! :)
