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.

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

What are the terms of participating?

Please refer to the official rules for the qualifier contest:

How many entries may one person make?

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

Can I use any data?

This qualifier contest allows for any data. Please ensure the data set(s) you choose are related to the theme. 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 with subject line 'Eligibility Question.'

Am I required to make my data set(s) or viz downloadable?

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.

Who can I contact if I am having problems with Tableau Public?

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

How will the winner be chosen?

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.

Will I receive my scores?

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

Can I receive feedback on my work?

Feedback is available upon request by completing this form.

Why isn't my country included in the list of eligible countries for participation?

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 2025 and beyond.
