Perhaps it was the fact that this was a formal competition or that I spent more time than previous visualizations, but something about this contest allowed me to really up my game. So, while none of them won, I learned so much in creating them, taking a big leap forward in my development, so it was well worth it.

While we wait for the 2021 Iron Viz to take place, relive all of the excitement from the world's largest data visualization contest from 2020. The "environment" category produced some incredible data visualizations from our talented community members.

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.

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 public@tableau.com, 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?

We will publish the scores for the top 10 vizzes on the Tableau Public blog. Scores for the Top 100 entrants can be provided upon request after the contest is over.

Can I receive feedback on my work?

Yes, all entrants will receive their scores after the contest is over. The 'top 10' are eligible to receive additional feedback directly from the judges.

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

Some countries are not listed because of peculiar requirements to run a sweepstakes like Iron Viz.

Why are the scores I received in my feedback email higher than the scores of the top 10?

All submissions are scored by a panel of judges. The average of these scores is what you see in your feedback email. From those scores, the ‘top 10’ submissions are identified and provided to a panel of industry expert judges. The scores from this panel are what you see in the results blog posts.
