I wrote another post for the Data Visualization Society (DVS)'s Medium Nightingale entitled Data Visualization for Audiences in Low- and Middle-Income Countries, which summarizes a related discussion I moderated in June 2019 on the DVS Slack. The discussion was interesting and helpful to hear about others' experiences. I really like this quote, which I think is important to keep in mind.
“One guiding principle I have is that the graphic is only as useful as the audience finds it. This principle has two implications: 1) that feedback and revision is essential in the process of making an effective graphic and 2) that audience understanding/acceptance should have greater weight in making decisions than design preferences.”
The article was a Medium selected read for Data Science.
