I believe the answer is:

acute angle

I'm a little stuck... Click here to teach me more about this clue!

'can't be seen in square for example' is the definition.
I can't judge whether this definition defines the answer.

'a charming view' is the wordplay.
'charming' becomes 'cute' (I've seen this before).
'view' becomes 'angle' (angle is a kind of view).
'a'+'cute'+'angle'='ACUTE ANGLE'

'that' acts as a link.

Can you help me to learn more?

(Other definitions for acute angle that I've seen before include "tighter corner" , "That can't be right - it's smaller" , "Meeting point" , "That's not right" .)

I've seen this clue in The Guardian.
