I wanted to share an interesting data visualization experiment that Susie Lu is doing in her spare time for fun.

Susie Lu is a Senior Data Visualization Engineer with Netflix. She has been doing some data visualization prototypes with grocery receipts.

The grocery receipts are made with thermal printing; no ink is used. The prototypes were created by connecting a printer via USB to her computer. The printing protocol was made accessible to her in JavaScript with a thermal print design created by Sam Saccone.

Here are some screenshots of some of her prototype testing.

I think Susie’s experiment is very creative and something for all of us to think about in how we can visualize common things like grocery receipts.
