On his blog visualisingdata.com, Andy Kirk has published a series of blogposts around the ‘little of visualisation design’, in which he focuses on the little details that make a huge difference. If you haven’t read it yet, go on Andy’s blog now, and then come back to thank me, you’re welcome.
I’d like to replicate the exercise and highlight some of the awesome details I saw in the entries of the data visualisation competition Iron Viz. This list is not exhaustive ; if your viz is not included, that doesn’t mean I didn’t like it. The quality was fire this year. Besides, my goal is not to list my fave viz, just a couple of details that made me chef kiss my computer on a Sunday afternoon and even, consider opening a YouTube reaction channel where I shout my love of other people’s dataviz sprinkled with French swear words (solid concept eh?).
Trends I notice this year in Iron Viz:
- A good year for horizontal scrolldown, not an easy format at all – yet, you guys rocked it
- Many clever techniques to reveal the viz little by little, via click actions required from the user
- Lot of entries exuded fun.
9 details I loved about 2022’s entries
- The selective art of colours
- Be daring with boring charts
- Using the colours and design of your topic in a tactful manner
- When your chart type evokes the topic you are covering
- Selecting the right datapoints
- Documenting via a video / audio guide
- How not to make your viz look as complex as it is at first sight
- How to encourage the reader to re-visit your viz with a new pair of eyes
- Fun in dataviz
1/ No, you don’t need 9 colours to convey meaning
2/ Some charts should be banished… nah actually, all charts have a use case, you just didn’t know
I very rarely see the point of treemaps. However, it is possible that Dinushki De Livera’s converted me because her Colors of Van Gogh makes a good use of them to reveal colour palette progression in Van Gogh’s work.
Meanwhile, I genuinely don’t get the hate pie charts get and don’t even @ me, I’ll tear you down on this one. It brings so much joy to me that Jessica Moon’s used a new combo, let’s call them lollipies in her Comedy in Huntsville, AL.
3/ Taking design elements from your topic… while creating your own identity: the colour palette edition
Shout out to Wendy Shijia too, who used tactfully Google’s colour palette in her Learning about the world through doodle art viz: Google’s logo colours are hard on the eye, especially if you put the blue and red next to each other, they vibrate. Receding the colours (I can’t remember the technical term, please don’t sue me :D) is a detail that makes a huge difference.
4/ When your design and your topic merge: chart types
I like nothing more than a classic chart which designs ties with the topic. For instance, I used lollipop chart in the shape of trees in my geocaching viz, cause you know, geocaching is an outdoor activity.
5/ The right datapoints
On Twitter, everyone praised Kim Tricker for her sleek design on her Women in Film. I totally agree of course, but I have to say, I was even more impressed by how compelling her storytelling is with just a few cleverly selected datapoints. You absolute Queen.
6/ Accessibility and storytelling
I added an audio transcript in one of my vizzes recently but Emily De Padua went so much further in the 19′ listener guide of Color Studies. A special shout out for this one, because, once you finished a viz, the last thing you want to do is to spend more time recording and explaining it. And yet, it’s a precious thing. THANK YOU.
7/ There is an art in enticing the reader in a complex viz
CJ Mayes, The art of conversation: so many details in the design recede (the instructions, the dotted lines between the sections etc.) to help you immerse. And then BAM, you realise the viz is actually 10x more in-depth that you thought at first.
8/ Storytelling like an onion
Nathalie Richer, Women Artworks at MoMA: what a classy execution. The horizontal scroll works so well here and I am usually not a fan. I love the fact that you have to click for details but even more, when you finish the viz, those spiders that invite you to re-visit the viz, such a neat idea!
9/ Practitioners just want to have fun
I love how Annabelle Rincon’s Tintin in the Data World includes an engine to translate the name of Tintin in… your own language or other languages like latin. You know, in case you need to go back to Ancient Rome and have a conversation about your favourite Tintin characters 😀
I’m gonna finish my tour with Will Sutton, Interpreting Art: this sparks so much joy. The fact that there’s a quiz at the beginning, creates a strong “what about me (and my results)” component and entices the reader in the topic.
That’s a wrap folks!
Final note: many countries are not eligible for the global #ironviz qualifiers, therefore disqualifying many talents in the world. For instance, it would be shame not to give more visibility to Idris Akilapa’s Afrobeat & Afrobeats, a viz that gave me an intro on a topic on which I have absolutely 0 knowledge. That’s what I love the most about those competitions!
