This distinction between designer-centric and reader-centric has echoes of the distinction between "bottom-up" (perceptual) versus "top-down" (cognitive) in the saliency literature.
True. I find that in visualization literature, we have a lot of information about bottom-up at the level of individual features but we do not have a good sense of how all these low-level components lead to a perception of specific thoughts and messages. The higher you go in the cognitive hierarchy, the harder it gets to be specific about mechanisms.
>For example, even a simple change from a bar chart to a pie chart requires transforming the value from absolute values to relative values, expressed in percentages.
Maybe I miss something, but also for bar charts you need to transform absolute values to percentages and then display units :)
Interesting ideas! I would like to receive updates about the course. Thanks!

Only if the bars represent a percentage; otherwise, they do not. I'd be happy to add an example later on. Sorry, I have to run now! :)
