Having been corrected, Chapter One divided circle (3,5)
I believe the answer is:
pie chart
'divided circle' is the definition.
(I've seen this before)
'having been corrected chapter one' is the wordplay.
'having been corrected' is an anagram indicator.
'one' becomes 'i' (Roman numeral).
'chapter'+'i'='chapteri'
'chapteri' with letters rearranged gives 'PIE CHART'.
(Other definitions for pie chart that I've seen before include "Illustration of shares" , "Display of information" , "Circle divided by radii to depict percentages of the whole" , "Graph of a circle divided into sectors" , "Display of data r" .)
