look round

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

'from casual survey' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'appear fat' is the wordplay.
'appear' becomes 'look' (synonyms).
'fat' becomes 'round' (round can mean fat or plump).
'look'+'round'='LOOK-ROUND'

Can you help me to learn more?

(Other definitions for look round that I've seen before include "The Globe should do this" , "inspection" .)

I've seen this clue in The Guardian.
