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:
- Design
- Storytelling
- 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.
