Each trip, suspect produced graph (3,5)
I believe the answer is:
pie chart
'graph' is the definition.
(I've seen this before)
'each trip suspect' is the wordplay.
'suspect' indicates anagramming the letters.
'each'+'trip'='eachtrip'
'eachtrip' anagrammed gives 'PIE CHART'.
'produced' acts as a link.
(Other definitions for pie chart that I've seen before include "Display of data r" , "Illustration of shares" , "Circle divided by radii to depict percentages of the whole" , "Display of information" , "Graph of a circle divided into sectors" .)
