The figure, unfairly rag the new maid about (7)
I believe the answer is:
diagram
'the figure' is the definition.
(I've seen this before)
'unfairly rag the new maid about' is the wordplay.
'unfairly' indicates an anagram (I've seen this in other clues).
'the new' indicates an anagram.
'about' is an insertion indicator.
'maid' with letters rearranged gives 'diam'.
'rag' anagrammed gives 'agr'.
'agr' inserted within 'diam' is 'DIAGRAM'.
(Other definitions for diagram that I've seen before include "Explatory drawing" , "I'm a drag (anag)" , "Line drawing" , "Simple schematic" , "Simplified representation" .)
