Planner who produces a graph? (7)
I believe the answer is:
plotter
'planner' is the definition.
(plotter is a kind of planner)
'produces a graph?' is the wordplay.
I cannot quite see how this works, but
'graph?' could be 'plot' (graphing is a kind of plotting) and 'plot' is present in the answer.
The remaining letters 'ter' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'who' is the link.
Can you help me to learn more?
(Other definitions for plotter that I've seen before include "One who schemes" , "Schemer" , "Conspirator" , "Conspirator's" .)
