I have asked a question like this before [in Workplace](https://workplace.stackexchange.com/q/49388/26826), but this time is only about diagrams specifically, and on formal work generally. Some answers in there say that I can use the Venn diagram if I make it less childish (drawing by a program, not by hand).

I really like to increasing productivity and efficiency. In his book _The Back of The Napkin_, Dan Roam argues that to pictures is a power tool to solving problems and selling ideas. I have seen pictures used in solving problem works (e.g. research papers), but never seen them in formal selling idea works (e.g. cover letter, SOP). I want to know if adding them in any formal writing is good or not.

For example, when talking in a cover letter about how relevant the field I study and the skills the job require, I think using this Venn diagram is effective (imagine this is drawn by a program): ![image description](https://i.stack.imgur.com/mpBaE.png)

And now, in the personal statement I will use to apply to a grad school, when I talking about how I work smart, not work hard, it is best to illustrating the point with this: ![image description](https://i.stack.imgur.com/wjwjZ.png)

Let alone the space they require, what do you think?
