Team Tableau Public
- August 5, 2019

The results are in for the second Iron Viz global qualifier! We received 101 entries—the most we’ve ever received for any Iron Viz competition. There can only be one winner but everyone who participated should be extremely proud of their work! Read on to find out who will be advancing to compete live on stage for the Iron Viz Championship at Tableau Conference 2019 (#data19) in Las Vegas.

For this qualifier, we challenged you to visualize music data using any public data set of your choosing. We’re excited to announce that 46% of the submissions were from first-time entrants!

How the judging works

Iron Viz judging has been a hotly-debated topic in the community. In an effort to be as transparent as possible, we’ve summarized how the process works.

First-round judges from the community scored each viz, narrowing the list to a Top 10

We asked Tableau Ambassadors, Zen Masters, past Iron Viz finalists, and others active in the community to help us narrow down all 101 entries to a Top 10 that advanced to our final-round guest judges. With more entries than ever before, we appreciate the thoughtfulness of our first-round community judges and their commitment to being fair.

A huge THANK YOU to these first-round judges who volunteered their time and expertise: Corey Jones, Emily Kund, Emma Whyte, Lilach Manheim, Simon Beaumont, Siroros Roongdonsai, and Steve Wexler!

Each entry was scored by multiple judges to minimize any potential bias. After the judges scored entries on Analysis, Design, Storytelling, each score was converted into a percentile rank for each judge. Each of these percentile ranks were then averaged across all judges. This method helps ensure that the scores are fairly distributed and not impacted by any one judge’s propensity to score easier or harder than others.

Final-round guest judges scored the Top 10 vizzes and selected a winner

Next, our final-round guest judges independently reviewed the Top 10 vizzes and scored each based on the same criteria as the first-round judges. THANK YOU to our guest judges Alberto Cairo, Nicholas Rougeux, Tom Barber, and Valentina D’Efilippo.

“When I was approached to be a judge for Iron Viz, I was excited to see the creative ways people would visualize music and I wasn't disappointed," commented Rougeux. "Each entry took me on a journey about a different set of music and opened my eyes to new visualization techniques I wasn't aware of—the whole process was a fantastic learning experience."
