We recently discussed "Ethics in Data Visualization" in my class. Here are a few excellent resources that I used:
1. Correll, Michael. "Ethical dimensions of visualization research." CHI 2019.
2. Cairo, Alberto al 2014. “Ethical infographics In data visualization, journalism meets engineering.”
3. Ten Considerations Before You Create Another Chart About COVID-19 by Amanda Makulec.
4. Cairo, Alberto. How charts lie: Getting smarter about visual information. WW Norton & Company, 2019.
