Thank you to everyone that has participated in or supported #IronQuest so far.

I didn’t run a challenge last month due to the Iron Viz ‘Agriculture’ feeder; the first feeder for this years’ main Iron Viz competition.  I hope you had the opportunity to explore the dataset provided by Tableau but I appreciate it wasn’t an straightforward topic to viz so well done to everyone who managed to enter. There is a short break between Iron Viz feeders 1 and 2 which gives us just enough time to squeeze in another #IronQuest round!

Thank you also to everyone who voted in the recent #IronQuest theme poll which I ran on Twitter. I’m excited to announce that for this round we’ll be visualising “Sea Creatures”, as selected by 50% of those who voted:

Iron Quest - Creatures Poll - May-June 2019
Iron Quest ‘Creatures’ Theme Twitter Poll


Animals always seem to be a popular viz choice so I thought it would be fun to turn this into an Iron Quest theme. I’ve no doubt you’ll all find interesting topics to visualize for the ‘Sea Creatures’ theme!

How can I enter?

The process is simple:

  1. Source your data and build a viz that somehow touches upon the chosen theme for the month.
  2. Upload your viz to Tableau Public or somewhere where it can be openly viewed online.
  3. Fill in the submissions tracker here so we can keep track of who is participating. This step is essential if you want to request feedback or be credited in the wrap-up blog post.
  4. If you opted in for feedback in step 3, the guest judge and myself will provide some constructive feedback on your viz after the submission period closes.

Top Tips:

  • You can use any data set which fits the theme (as long as you have permission to share it publicly).
  • Always remember to credit your data source/s on your viz.
  • Refrain from using any images or logos on your viz unless you have permission to do so.
  • Remember the Iron Viz judging criteria and try to focus on all three; Design, Storytelling and Analysis. 
  • Think outside the box!

Data Sources

If you are struggling for ideas, here are a few data sources to help you to get started. These are just a few potential sources you could use. Feel free to source your own data as necessary.

Who is my guest judge?

I’m excited to announce that I’ll be teaming up with fellow Tableau Social Ambassador Mark Bradbourne this month!

He is a co-leader and regular speaker at the Cleveland TUG, founder of Mentoring Meetup (a site which helps to match mentors with mentees), regular participant in community projects such as #MakeoverMonday and blogger at

When is the submission deadline?

The deadline for submissions has been extended until midnight PST on Wednesday 12th June 2019. Feedback will be provided (to those who request it) by Mark and I in mid-June.
