There's actually a Think Data Thursday coming up about visualizing Survey Data with Tableau Zen Master Steve Wexler Think Data Thursday: Jump Start Visualizing Your Survey Data Using Tableau
and the Survey Data user group.
(thank you Susan Baier, I found most of these resources on an old post of hers.)
Visualizing survey data in Tableau takes some specific data prep and the resources above will help point you in the right direction.
Thanks for your response. It looks like there's a lot of great information in that group.
