#DataDiscussions with Rodrigo CalloniData Discussions with Rodrigo Calloni

In this week's #DataDiscussions we had the pleasure to host Rodrigo Calloni. 

Rodrigo works as a Learning and Knowledge Specialist at the Inter-American Development Bank and has a great passion for data visualization and Tableau.

You can learn more about his Tableau journey by reading his personal blog tableauing.wordpress.com or by following Rodrigo Calloni on Twitter.


Question 1 - What is your job/role? How do you use Tableau as part of it?

Rodrigo Calloni: My employer gives me the fancy “Learning and Knowledge Specialist” tagline. Before that, I used to be a System Librarian which summarizes my formation and skillset a bit clearer in my opinion. I am a Librarian Scientist by formation but since the beginning of my career, I was always dedicated to learning all about systems, servers, databases, building reports etc. Tableau entered my life in 2014 when we started the process to launch an Open Data portal for my institution. My use of Tableau is to help folks at my institution to get faster and easier access to the usage of their products. But that is only a small part of what I do (kind of 10%). I hope I could flip the game and dedicate 90% of my time on finding insights that could help us improve our business. 


Question 2 - If you could give one piece of advice to a new Tableau starter what would it be?

Rodrigo Calloni:  The best advice is to join the community whenever it is (Twitter, Forums, data.world, etc) and ask for feedback until you start to figure out things by yourself. Tableau is a great tool but it takes some effort to change your spreadsheet mindset and to start understanding the visual capabilities of your data.


Question 3 - If you could add a new feature to Tableau, what would it be?

Rodrigo CalloniCustom Fonts. I love typography and the downsize of Tableau for me is the limitation on how we can use fonts. The worse feeling is when I publish a viz and when I look at a co-worker computer it is all messed up because him/her doesn’t have the proper font installed. It makes me cry all the time.


Question 4 - Favourite viz you have made?

Rodrigo CalloniI need to be very selfish and say it is my own Tableau Resume. After I ended it up I found out that I had discovered my style and since then I am trying to stick with most of the elements of it on my vizzes.


Question 5 - What’s the best data book you’ve read recently?

Rodrigo Calloni: You may be thinking he is a super reader, one book a day, after all, he is a librarian… Well, not really. Since early school, I was never a great reader. On the other side, I was always great on understanding stuff very quickly. Also, I am super hands on and I am a learner by practice. Back to the question, I got The Big Book of Dashboards as a valentines day gift last year and I read parts of it, in special when I was looking for specific solutions for my dashboards. Instead of reading books I learn a lot by watching videos of people doing vizes on Tableau, in special those from Andy Kriebel. I am afraid he may have stopped the series now, I really miss his tutorials on Tableau Tip Tuesdays
