First: Introductions

Goal: Start collecting data from your life so that you can visualize it!

Hand-Drawn Data Viz

  • Once we have collected data, a common next step is to visualize it.

  • Two key aspects of data visualization:

    • Determining how you want to display the data.

    • Figuring out how to tell the computer to do that mapping.

  • Hand-drawn data visualizations allow us to focus on the first part with full control over the creative process!

Dear Data

“Each week, and for a year, we collected and measured a particular type of data about our lives, used this data to make a drawing on a postcard-sized sheet of paper, and then dropped the postcard in an English”postbox” (Stefanie) or an American “mailbox” (Giorgia)!“

Goal: Over the next few days, collect data from your life so that you can visualize it on Lab 1.


Recommendations

  • Store the data in your favorite spreadsheet program (Google Sheets, Numbers, Excel).

  • Determine what your cases/observations will be.

  • Collect data on more variables than you will likely visualize. It is hard to know beforehand what the interesting relationships will be.

  • Come to my office (Library 390) to borrow art supplies (colored pencils and felt-tip markers)!
