We are less than one week away from crowning a new champion of the world’s largest data visualization competition. This year, Iron Viz is in-person and virtual. Whether you’re heading to Vegas or tuning in from your computer, it’s time to get organized and maximize your viewing experience. Do you know how to participate in live voting?

What is the judging criteria?

Judging is based on three areas: analysis, design, and storytelling. During the live broadcast, each finalist will have 20 minutes to build their visualizations and can earn a potential total of 100 points. Our judges will allocate 90 of those points, and the last ten points are up to you. The individual with the highest number of points will be crowned the winner.

  • Design: How appropriate is the design for the story 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?

Be sure to cast your vote for your favorite viz—text to vote numbers will be announced when the voting window opens during the live event. Visit for more details and check out the official rules.

Special thanks to our judges this year—Tableau VP of research and design Dr. Jock Mackinlay, Tableau Public Director Taha Ebrahimi, and the 2021 Iron Viz Champion Lisa Trescott.
