[GUI-Talk] WP Survey recommendation request

[Starry Sky]

Hi all,

Does anyone have a good recommendation for a free Wordpress survey plugin (or options) that is accessible to the survey taker?  I would like to create a complex survey with the ability to categorize the raw data into output graphs and summaries of the results.  Hopefully folks on this list have a good suggestion for a free yet robust survey plugin that is also accessible...or is that combination too much to ask for?

Thanks much!

Skye
