Ask HN: communicating a set of positive responses to a user survey?

I just tested out a prototype of a web application I'd been working on with about 500 users, and got some very positive survey feedback-- something like 90% of responders want to use this in the future, and I got a lot of enthusiastic and very encouraging comments. Most of the 10% who responded neutrally-to-negatively sited a fixable technical issue with the application.

I'm looking for a striking way of communicating this initial result to pitch this informally to some coworkers of mine. I'd like to give an impression of the overwhelmingly positive tone of the comments, as well as a visual sense of the ratio of positive to neutral to negative responses.

I must communicate this efficiently, because I do not expect my coworkers to spend the time to read a full write-up, but I would like to muster some support for my idea.

What is an effective way of displaying this information-- an infographic? Just text? Any suggestions?
