Diagram (5)
'diagram' is the definition.
(I know that chart is a type of diagram)
This is all the clue.
(Other definitions for chart that I've seen before include "[LOVE ME DO] became the first of many to ..." , "Visual display of information" , "series of plots?" , "Hit parade" , "Navigational map" .)
(Other definitions for graph that I've seen before include "Plotted diagram" , "Diagram showing the relationship between variable quantities" , "Geometrical diagram" , "Drawing showing relationship between quantities" , "A plotted chart" .)
