It's not too late to cast your ballot for one of the Chicago entries in the User Group Viz Contest. We have until June 30th to vote. You can only vote once but anyone can vote. You don't have to be a member of the user group. So, if I were KK or Julianna I'd start asking everyone I know to vote for my viz. You can help, too, by asking your colleagues to vote at http://www.tableausoftware.com/forms/viz-contest-voting.
There are some amazing examples there but we know who's the best, don't we, KK & Julianna?
