Google Docs experiments with automatically generating response summaries for forms. If you edit a form and click on "View responses", Google shows charts for questions with multiple choices and lists the first answers for free-style questions.
The summaries are pretty basic but they reveal more information than the raw data. Hopefully, until the feature is officially launched, Google will make the summaries interactive and customizable and users will be able to publish them.
