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!
“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)!“
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)!
