Thomas Lüthi

After a master’s degree in English and Business Administration at the university of Bern, Switzerland, Thomas worked as a linguist and actor before joining the Data School. Fed up with endless auditions and nonsensical machine translations, he decided to focus his creative energy on a new career path. When he came across the Data School, he knew he had found the perfect place to combine his passions for storytelling and information technology.

Throughout his career he kept a creative outlook on the world, finding new approaches to problems and presenting his work in a manner that engages his audience. The joy of finding new insights, breathing life into numerical data and making complex issues easy to grasp is what got him hooked on Tableau.

In his private life, Thomas is a jack of many trades although his mastery is questionable at best. He loves language, history and the creative arts and he likes to think of himself as a decent cook.

Bye-Bye, 25WS
It has been four months since DS11 started their training at 25 Watling Street. Four months in which we were taken from complete newbies to fairly experienced users of the tools and processes that we now get to apply as we go out on placement

Structuring Word Clouds
Word clouds don’t have the best rep, but they can be a powerful tool to represent text-based data. There are tons of great manuals for how to build a word cloud in Tableau, so I won’t get into the details about that here. One thing I will say is that with word clouds, data prep is everything

A Tableau Visualisation of the Whole American Civil War
Over the holidays I finally had some time to pursue a passion project that had been on the back of my mind for some time. Being somewhat of a history buff, I have a great interest in the American Civil War, and I wanted to create a Tableau visualisation using data about that conflict

Using LODs to Calculate Customer Retention
This post looks at how we can display what percentage of customers is made up of return customers, and what percentage is new customers. To achieve this, I’m using Level of Detail expressions to essentially create bins of customers, depending on when they placed their first order

This post is based on a chart I made for this week’s Makeover Monday, based on projected age data about the US population. After reading it, you should be able to create individual reference bands for every pane in your view

A challenge I encountered when coming to grips with Alteryx was to rank records based on a shared value. For this exercise, we are trying to rank players according to their score
