Link: medium.com/@rcastillo90...

I have been asked where I learn from when learning Tableau, and I thought it would be a good idea to put my top 5 best resources!

I still use it at work and in my free time.

If you have someone who wants to learn Tableau but doesn’t know where to start, my blog post helps fill that gap.

Looking forward to bringing this to the #datafam

I'm really enjoying my RingConn 2 and love the UI experience. I can track everything for activities and sleep. It can also monitor sleep apnea, which is cool.

This is a viz I did on Saquon Barkley’s season and his Madden ratings for the upcoming game, Madden 26.

He had an incredible season in his first season as an Eagle and also won a Super Bowl ring. He obviously had a major impact on the team.

Looking forward to playing Madden 26!

No Shortcuts, Just Reps: The Real Way to Grow in Tableau Inspired by Sarah Burnett’s message on Tableau Mastery

In my blog post, I discuss Tableau Mastery and, in my experience, how I have been learning and practicing in Tableau. I can relate to this because I always like to do something for fun, and that is with Tableau.

Link: medium.com/@rcastillo90...

Sarah from @dubdubdata.bsky.social said on Tableau Mastery, “Want to be great at Tableau? Not just good, but great. Here’s what we see in the best: passion, curiosity, attentiveness… And most importantly, they do the homework, then they do the extra homework”

I believe this 100%, and it is one of the things I wish I had done early in my data journey before I got my first data role. I'm fortunate to be in my role and always willing to share advice and tips with others because I know what it is like not having someone to guide you in this data space.

A poster showing icons for 40 different visualization types, categorized by goal – e.g. "showing shares" or "showing flows" or "showing developments over time".

📊 There are *so* many chart types out there. Which one should you use for what kind of data and goal?

I tried to answer the question in a new blog post (and poster!): www.datawrapper.de/blog/chart-t...

I'm back in my home state after a great Outlier conference in Miami!

I am happy to be part of the volunteer team and assist with the conference's setup and everything.

I had a great time there and was able to explore in Miami.

#Outlier2025 has been great so far, with many perspectives on data visualization. The tools used to display data amaze me; as someone who uses Tableau, it is a good perspective.

No offence to everyone else here at #outlier2025 but a talk by @datarevelations.com is basically the highlight of any conference - worth the entry fee alone!
