🧑‍🍳‍ Why you should try Iron Viz

In true #IronViz fashion - the motto is Win or Learn, you don't lose! Even if you have been using Tableau for years or just getting started in the community, there's so much to learn from everyone in this exciting annual event that gathers the greatest minds of data visualization! You can also check out this page on past Iron Viz submissions - a word of caution though, once you start you can't stop! ;) If that's not enough, check out these interviews and resources that will give you a glimpse into the process of making your submission!

💡💡 Parting wisdom from the team

From Will
Design

Divide your viz up into sections or chapters. This makes it much easier for the judges to understand and assess the points you trying to make. Use layout, spacing or visual breaks to mark transitions between chapters (e.g., horizontal bands, slide-style panels, background colour shifts). Keep consistency of design across chapters (fonts, colours, chart style) so the user isn’t distracted.

Storytelling

Add some emotion, stories aren't flat like "we did this, then this happened, this is what we learned". They often twist and turn and crucially make you feel something, often you will hear many negative personal stories to drive empathy in your audience. However you can make the emotion joyful, or comedy that would help an entry stand out. But balance emotion with clarity: the emotion should support the story and analysis, not overshadow them. Consider using a personal story to make the data more relatable.

Analysis

Make each chart make a point. And that point shouldn't be "what happened" but "why it happened" or "what it means" to your reader or the story. Avoid creating charts just because you can, each one should link back to the story or take the reader on journey through your viz.

From Louis
Design

I'm a big fan of thematic designs and it's a very useful trick to add something playful but leveraging on pre-attentive attributes. Once your audience know how it works (make sure you it's intuitive or well explained), you can use an icon or color in place of lengthy text to direct where you want your audience to see.

Storytelling and Analysis

One of the best advice I got was falling back to the 4MAT framework. That is:

  • Why is this important?
  • What affects this?
  • How does this affect us?
  • Where do we go from here.

With this simple framework to guide both your storytelling and analysis, you can ensure a coherent flow of thoughts.

Hi, Louis here! Have been working in various industries in the past decade but finally found my way into the video game industry as a Senior Data Analyst, driving customer insights and building dashboards for 2K Games. I always enjoy a good game with an immersive narrative, which probably explains why I am passionate about bespoke designs and the storytelling potential of data vizzes!
