That's a great question.
Here's an example I just threw together. Someone presents these anual projections in a meeting and suggests that the projected anual growth seems to be slowing down between 2026 and 2028.
- Does the data support this claim?
- Between what two years did the projections double?
- (my favorite question to ask) What data isn't shown?
I don't think you'd have trouble answering these questions, but I'm curious about the types of questions and challenges people generally face when reading and inspecting data presented graphically.
There is extensive literature on creating data visualizations and some on detecting manipulations within them. However, there seems to be much less content on data visualization literacy, a skill I believe is more commonly needed than creating data visualizations.
I'm considering a blog article on this topic.
