Well, but this one looks like a special type of graphs
to me:

  "Specifically, a method and apparatus are provided for
   using dynamic graphs wherein the computer user is 
   able to manipulate the graph shape directly, which in
   turn not only modifies the graph, but also alters the 
   corresponding and underlying tabularized data..."

IMHO this patent covers dynamic spreadsheet manipulation 
using pie charts but not the representation of data in
pie charts in general. Do you agree? ;-)
