A good hand graphically represented (11)
I believe the answer is:
calligraphy
'a good hand' is the definition.
(thesaurus)
'graphically represented' is the wordplay.
'represented' indicates an anagram.
'graphically' with letters rearranged gives 'CALLIGRAPHY'.
(Other definitions for calligraphy that I've seen before include "Decorative handwriting as an art" , "Beautiful script" , "Beautiful handwriting" , "Fine penmanship" .)
