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. 

The 2025 Iron Viz Qualifiers theme is entertainment. Entertainment is any activity or performance designed to provide enjoyment. It can take many forms, including movies, television shows, music, sports, games, and theater.

For questions on whether your data set meets the theme criteria, please reach out to ironviz@tableau.com with subject line 'Theme Question.'

Please refer to the official rules for the qualifier contest:

• Iron Viz Qualifier Official Rules

One entry per person. If you need to make changes to your viz after submitting, please make those changes prior to the submission deadline.

This qualifier contest allows for any data. Please ensure the data set(s) you choose are related to the theme.  Looking for a dataset that’s ready for stardom? Check out the Data + TV and Data + Movies starter kits, powered by datasets from IMDb with millions of entertainment data points to leverage.

Please be considerate of others, and do not use a data set that might be found overly offensive. We would also like you to consider image rights when including visuals in your visualization. For specific eligibility questions, please reach out to ironviz@tableau.com. 

If possible, provide a link to your source(s) in the footnote or description of your viz and allow 'Download' for the viz you submit. This allows others to learn from your work, just as you can learn from others. Making vizzes downloadable can be done by signing in to Tableau Public, click on the viz you created, and checking the box "Allow workbook and its data to be downloaded by others", then click save.

You may contact Tableau Public at public@tableau.com, please include Viz Contest in the subject line. Note that submissions can only be made via the submission form.

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

Feedback is available upon request by completing this form.

We strive to open Iron Viz up to everyone in the world. Unfortunately, due to limitations we must limit Iron Viz to those countries that are listed for this year. We continuously assess our eligible countries to be as inclusive as possible, and we hope to add more countries for 2026 and beyond.

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.
