Sometimes I see articles, even high-quality ones, use illustrations (e.g. imagine a simple Powerpoint depiction of a certain process).
I'm now writing my thesis and found some interesting illustrations that I would like to use in the Definitions section of my thesis. However, I'm not quite sure if that would turn out to be beneficial:
pro: It would break up the wall of text a bit and provide a more intuitive way of grasping a definition.
con: My supervisor (who probably would not bother to read the whole section anyway) glances over it and doesn’t like illustrations and marks me down.
I don't really want to ask my supervisor about this, since he is a highly decorated senior professor and head of faculty. I'd rather use my “capital” wisely on methodological questions.
What is your view on that?
