Iron Viz

What is Iron Viz?

 

Iron Viz is the world’s largest data visualization competition. What began as a breakout session at Tableau Conference 2011 has grown into a global phenomenon and become a core part of the Tableau Community. Three Iron Viz contenders take center stage and have 20 minutes to tell the most compelling story using the same data set. Like the qualifier leading up to it, contestants’ vizzes are scored based on analysis, storytelling, and design. It is something you must see to truly understand.

Iron Viz FAQ

Iron Viz is the world’s largest data visualization competition. Three worthy contestants take center stage in front of a global audience and have 20 minutes to deliver a compelling and awe-inspiring story using the same data set. 

Iron Viz, the world's largest data visualization competition, is held on the keynote stage at Tableau Conference every year. The three finalists are selected from a global qualifier competition, which usually happens towards the second-half of the year and is open for one month long.

A panel of judges comprised of Tableau ambassadors, previous Iron Viz finalists, data viz experts, and guest judges will evaluate all submissions based on the following criteria:

  1. Design
  2. Storytelling
  3. Analysis

Analysis will be the tiebreaker in case two vizzes have the same overall score. Should the Analysis score also be tied, the panel of judges will make a final decision.

Scores and feedback can be provided (upon request) by filling out this form after the contest is over.

Iron Viz: Student Edition is a competition open exclusively to students, though we encourage you to participate in both! Iron Viz: Student Edition is intended for college students looking to develop their viz skills in a challenging setting with their peers before jumping into the greater vizzing community with Iron Viz. This competition is a great introduction into the world of viz competitions. Iron Viz: Student Edition winners will have the opportunity to connect with members of the Tableau Community with a funded trip to Tableau Conference.
