le August 12, 2021

The results for the 2021 Iron Viz Qualifier Contest are in. This year, we challenged you to visualize data on a topic you love, and it was fantastic to see the diverse range of passions on display throughout the entries. Participants covered everything from sports, movies, travel, and music to subjects such as tree health and covid-19. (As a reminder, you can see all the entries for this year's contest here.) Only three will advance to the virtual Iron Viz Championship at Tableau Conference in November. Who are these talented data storytellers? Read on.

The judging

We asked Tableau Ambassadors, Zen Masters, past Iron Viz finalists, and other active community members to help us narrow down all 320 mind-blowing vizzes to a Top 10. Entries were scored according to the following criteria:

  • Design: How appropriate is the design for the story that is being told?
  • Storytelling: Is there a clear story being told or a question being explored, and is there appropriate context?
  • Analysis: How sophisticated and appropriate is the data that is being used for the story?

Thank you to our community judges: David Pires, Marc Reid, Adam Mico, Heidi Kalbe, Neil Richards, Seffana Mohamed-Ajaz, Karen Hinson, Ravi Mistry, Eric Balash, and Courtney Guc (Tableau).

Next, our final-round guest judges independently reviewed the Top 10 vizzes, scored each using the same criteria as the first-round judges, and selected three finalists. Thank you Simon Beaumont, Tim Ngwena, Timothy Vermeiren, Bridget Cogley, and Lindsay Betzendahl.

Taking the Iron Viz challenge is no easy feat. Participants spend weeks sourcing and preparing their own data, trying new techniques, and pushing their skills to the limits to create the ultimate visualization and share the story behind it. We are so proud of their dedication and awestruck by their accomplishments. Take a look at the Top 10 entries below:
