Tableau Visualization
Tableau is arguably the biggest deal now in terms of data visualization for non-programmers. Let's pretend you are not a programmer. Learn and experience what it is like to make visualizations using Tableau to answer the same questions about your classmates in our course.
For each of the questions, think about what chart you should use to convey your answer and make your best effort to create something that makes sense to you. There's no right or wrong. When we meet in the class again, we will set aside time for each team to discuss and compare the variety of visualization solutions each member has come up with for the same set of questions. It will be fun!
To include a Tableau visualization in your report, take a screenshot, save it as an image,
put it in the learning/week2 folder, and replace  with
your own image. Please makes sure your screenshot includes the entire Tableau interface
including the controls, widgets ...etc.
