Who doesn’t love maps?
Maps help us make sense of the world. Maps enable us to explore far-away lands without leaving our homes. Maps help us to reveal interesting relationships and unique insights in our data. What’s more, maps can be both beautiful and analytical.
If you haven’t already guessed it, the next round of #IronQuest will be focused on maps!
This is slightly different to any previous #IronQuest in the sense that we’ll be focusing on a chart type, rather than a specific topic this time. With that being said, the data you choose can be on any topic you wish. However, your viz must include at least one map. This is a great opportunity to experiment with some of the newer mapping features in Tableau or even experiment with building your own map styles in Mapbox! The choice is yours.
How can I enter?
The process is simple:
- Source your data and build a viz that somehow touches upon the chosen theme for the month.
- Upload your viz to Tableau Public or somewhere where it can be openly viewed online.
- Fill in the submissions tracker (embedded at the bottom of this post) 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.
- 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.
- You can use any data set which fits the theme (assuming 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!
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.
Many countries also have data portals that contain location-specific data focused on that country.
- Free GIS Data – a categorised list of links to over 500 sites providing freely available geographic datasets.
- ArcGIS Hub – search and download data shared by thousands of organizations around the world
- HumData – The Humanitarian Data Exchange
- Eurostat – European Statistics
- World Bank Open Data
- Public Geo Data for the UK
- CDC – Centres for Disease Control and Prevention

Who is my guest judge?
I’m very excited to announce that I’ll be teaming up with mapping extraordinaire, Jonni Walker this month!
Jonni is passionate about data visualisation and his creations using Mapbox and Tableau are things most of us can only dream about!
His work has been published in Andy Kirk’s “Best of Data Visualisation” round-ups multiple times and in Andy’s words, “He is doing things in Tableau I’ve rarely seen before with such creativity and with an aesthetic you might normally associate with that of centres of excellence like National Geographic magazine”.
Below is an example of Jonni’s work. This viz focuses on Sea Turtles in the Greek Islands:
When is the submission deadline?
The deadline for submissions is midnight PST on Tuesday 31st March 2020. Feedback will be provided (to those who request it) by Jonni and I shortly after the deadline date.
Thanks for reading and I look forward to seeing your entry!
