Data Viz Competition

Princeton Tableau Day - March 14, 2024


Let's celebrate Pi Day (March 14) by giving pie charts a makeover! In our Pie Chart Makeover competition, we invite you to explore alternatives to this classic chart type and to break free from its limitations. Whether you're a Tableau expert or a budding enthusiast, this competition is your chance to think outside the pie!

All participants will begin with the same starter workbook packed with pie charts and over 100 years of data on course offerings from four prominent universities in California. This extensive dataset offers a treasure trove of information waiting to be explored and visualized.


Dive into the history of academic disciplines and uncover their rise and fall over the last century. Use the provided data to analyze trends and discover insights that shed light on the changing landscape of higher education.

You can use the provided pie charts if you like, but feel free to discard them entirely and start from scratch. Your aim is to craft compelling visualizations that surpass the original.

To be clear: your final visualization does not need to include any pie charts at all.

Submit your entry by 11:59 p.m. ET, March 12, 2024, to be considered in the competition. Winners will be announced during Tableau Day on March 14.


Fabulous prizes await the winners of our Pie Chart Makeover competition!

  • 1st Place: Tableau hoodie and Tableau backpack
  • 2nd Place: Tableau hoodie and Data tote bag
  • 3rd Place: Tableau hoodie

Get Started

Download the starter workbook and let your creativity run wild! Additional information about the data is included in the workbook.

Evaluation Criteria

Entries will be evaluated based on the following criteria:

  • Design: The visual appeal, creativity, and usability of your data visualization.
    • Have you demonstrated design principles in your layout, use of color, and formatting?
    • Is the user experience intuitive?
  • Analysis: The depth of your data analysis and insights.
    • What questions have you asked, and how appropriate are your chart types, aggregations, and analyses in providing insight?
    • Have you identified trends, patterns, or outliers in the data and drawn meaningful conclusions?
  • Storytelling: The clarity and effectiveness of your narrative in conveying key findings.
    • Is the context and topic of the viz clear?
    • Is it obvious how one should move through the viz? Is there a logical flow?

Overall, participants should strive to create visualizations that are not only visually stunning but also informative, engaging, and easy to interpret.

The top three finalists, as determined by our judges, will be invited to present their visualizations live at Tableau Day. During the event, the audience will vote to determine who finishes in 1st, 2nd, and 3rd place.

How to Enter

All entries should be submitted through the Google form at: Pie Chart Makeover Submission Form

In order for your visualization to be considered, it needs to be published on Tableau Public. If you do not have a Tableau Public account, you can create one when you publish or sign up anytime on the Tableau Public homepage.

Important: Tableau Public is hosted by Tableau and is not a Princeton University website. No University data should be published to Tableau Public. After publishing your viz, go to the Server menu in Tableau Desktop and sign out of Tableau Public to end your session.

By default, visualizations published to Tableau Public are displayed on your public profile for all to see. If you prefer to keep your viz hidden, click the gear icon in the upper right of the published viz and turn off the "Show Viz on Profile" setting (the link will remain accessible by competition judges).
