Intrigued by Matthew's enthusiasm and nostalgic for the days when they tackled data challenges together, Ben decided it was time to explore Tableau once again.

Meeting Matthew from Tableau

A few days later, Ben and Matthew connected via video call. Greetings were exchanged, and Matthew wasted no time delving into the subject of their conversation. With a twinkle in his eye, he began reminiscing about their adventures as Tableau consultants over a decade ago. The memories flooded back, and Ben found himself reminiscing about those exhilarating times. Running around the world, solving Tableau challenges, and helping businesses see and understand their data—it was a time he would Never forget.

But now, Matthew had something new in mind. He wanted to put Ben's skills to the test. He wanted to know if Ben still had what it takes to create stunning visualizations and derive valuable insights from data. He challenged Ben to recreate a series of simple analyses in Tableau, with the stipulation that if Ben failed, he would have to publicly declare his love for 3D pie charts—a visualization technique that Ben despised.

Level One: Analyzing Sales Data

Matthew wasted no time in sending Ben the first challenge—an analysis of sales data. The task was to create a running sum of sales chart, showcasing the monthly sales trends and the impact of each day of the month. Armed with enthusiasm and the memories of his past Tableau adventures, Ben set to work.

After studying the data and pondering the best approach, Ben began creating the chart in Tableau. He implemented the running sum calculation and visualized it as a line chart, with each line representing a month.
