Each cohort (typically) gets a day in the week when they need to use a different data viz tool other than Tableau. For day 4, they can choose between Power BI, Qlikview, Google Data Studio, Flourish, and Looker.

Everyone hates telemarketers and robocalls. Fortunately, the FCC in the US has been tracking every consumer complaint about these calls back to Halloween 2014.

Rules:

1. Data prep can only be done in Tableau Prep.
2. Create a viz with their tool of choice and publish it to the web.
3. Write a blog post about their experience with the tool and publish it by 5pm.

Simple!
